Intermediate Raspberry Pi users have a project running. They understand basic Linux commands, can navigate over SSH, and have experienced the frustration of slow microSD boot times, running out of storage, or counting pins on a bare 40-pin header. This guide covers the seven upgrades that the r/raspberry_pi community and Jeff Geerling’s blog consistently recommend for users who have moved past the starter-kit phase.
The Picks
Raspberry Pi 5 (8GB)
The single most impactful upgrade for an intermediate Pi 4 user is the board itself — the Pi 5 runs roughly three times faster, gains a dedicated PCIe connector that makes NVMe storage possible, a real-time clock for server use, and a power button. Stocked at Adafruit and Micro Center nationally. r/raspberry_pi treats the Pi 5 8GB as the unambiguous answer to ‘should I upgrade?’ for anyone running a media server, PiHole, or print server on a Pi 4.
- Up to 3x faster than Pi 4 with 2.4GHz quad Cortex-A76 cores — immediately noticeable for transcoding, compile times, and web server workloads
- PCIe 2.0 connector enables NVMe SSDs via the M.2 HAT+, unlocking boot speeds up to 450 MB/s vs ~80 MB/s on microSD
- Built-in real-time clock and dedicated power button make it a proper always-on server
- Requires a new 27W USB-C power supply — the Pi 4’s 15W supply is not sufficient and will cause undervoltage warnings under load
- At current market prices, markup from scalpers can reach $150+ — buy only from PiShop.us, Adafruit, or CanaKit
Argon ONE V3 M.2 NVMe Case for Raspberry Pi 5
For an intermediate Pi 5 user who wants to move beyond a bare board on a desk, this case is the single-purchase solution: aluminum passive heatsink body, PWM-controlled 30mm fan, a bottom-mounted M.2 NVMe slot via PCIe FPC, two full-size HDMI ports, and a 3.5mm audio jack in one $49 enclosure. The Raspberry Pi Official Magazine gave it 10/10 and called it ‘highly recommended.’
- One enclosure replaces a bare board, passive heatsink, NVMe HAT, and HDMI adapters — no cable rats nest
- Software-controlled PWM fan via included Argon script; magnetic GPIO access flap with printed pinout built into the lid
- Full-size HDMI ports and 3.5mm audio jack correct the Pi 5’s most frustrating omissions for desktop use
- NVMe slot is exclusive — cannot use this case with a different HAT-style accessory on the PCIe connector simultaneously
- A handful of forum reports cite NVMe detection issues requiring a replacement lower-case part from Argon support
Official Raspberry Pi M.2 HAT+
For an intermediate Pi 5 user who already has a case they want to keep, the official M.2 HAT+ is the $12 unlock that transforms their Pi 5 from microSD-based to NVMe-booted. Sold at Adafruit and Micro Center nationally. PIP-compliant, guaranteed to work with Raspberry Pi OS out of the box. The 9to5Linux review title captured the community sentiment: ‘It Just Works.’
- At $12, the cheapest path to NVMe boot on a Pi 5 — dramatically undercuts third-party HATs
- PIP-compliant design ensures long-term driver support in Raspberry Pi OS without community workarounds
- Supports 2230 and 2242 form factors; compatible with both DRAM-less budget SSDs and AI accelerator M.2 cards
- Only supports 2230 and 2242 M.2 form factors — not the common 2280 size; pair only with drives in those sizes
- Does not include a case or cooling — the SSD and Pi board are exposed
Kingston NV2 1TB NVMe SSD
An intermediate Pi 5 user building a NAS or home server needs an NVMe SSD confirmed compatible — not all drives work reliably with the Pi 5’s PCIe implementation. The Kingston NV2 is explicitly called out as a reliable, tested option in Pimoroni’s own compatibility notes, the Geekworm wiki, and repeatedly in forums.raspberrypi.com threads. Its DRAM-less architecture makes it more stable on the Pi 5’s PCIe controller than some premium drives.
- Confirmed Pi 5 compatible across multiple community sources — not a gamble
- 1TB capacity is practical for a home NAS or media server; 2280 form factor fits the Argon ONE V3 M.2 case
- DRAM-less architecture avoids the power-spike compatibility issues seen with some DRAM-equipped drives on Pi 5’s PCIe bus
- DRAM-less design means sustained write performance degrades when the SLC cache fills — not ideal for heavy sequential write workloads like active video recording
- The Pi 5’s PCIe 2.0 x1 interface caps real-world throughput around 450 MB/s regardless of the drive’s rated spec
Raspberry Pi Sense HAT
The Sense HAT packs a gyroscope, accelerometer, magnetometer, barometer, temperature, and humidity sensor plus an 8×8 RGB LED matrix and a 5-button joystick onto a single GPIO-stacking board. It is the exact board the Raspberry Pi Foundation sends to the International Space Station for the AstroPi program. Stocked at Adafruit at $33. RaspberryTips.com gift guide lists it as a ‘must-have for any Raspberry Pi user.’
- Seven onboard sensors in one board — no breadboarding, no jumpers, no wiring errors; plugs directly to GPIO
- The AstroPi/ISS connection means thousands of documented, tested projects exist with the exact same hardware and Python libraries
- 8×8 RGB LED matrix gives visual feedback without needing an external display — immediately gratifying
- Occupies the full 40-pin GPIO header, blocking other HATs
- Temperature readings run ~5°C high due to heat from the Pi board itself; software correction is documented but requires calibration
Adafruit Pi T-Cobbler Plus GPIO Breakout
An intermediate Pi user comfortable with SSH but frustrated by counting GPIO pins on a bare 40-pin header will recognize the T-Cobbler Plus immediately from any Adafruit tutorial. Made by Adafruit themselves and stocked at Adafruit, Micro Center, and PiShop.us. Plugs into a breadboard and breaks all 40 GPIO pins into labeled, accessible rows. At under $8, the most impactful per-dollar add-on for anyone moving into physical computing.
- Pin labels printed directly on the board — T5V, GND, GPIO2 through GPIO27 — eliminate the GPIO pinout lookup step during prototyping
- Pre-assembled and includes a 40-pin ribbon cable; works with every 40-pin Pi from A+ through Pi 5 and Zero
- At $7.95 the most impactful per-dollar add-on for an intermediate user moving into physical computing
- The ribbon cable can stress connector pins during unboxing — inspect before first use
- No GPIO status LEDs — purely mechanical breakout, which is sufficient but basic
Official Raspberry Pi 27W USB-C Power Supply
Many intermediate Pi 5 users upgrade from a Pi 4 without replacing the power supply, then wonder why they see a lightning bolt undervoltage icon or erratic USB behavior. The Pi 5 requires the 5V/5A custom PD negotiation mode that only the official 27W supply provides. Stocked at Adafruit, Micro Center, and PiShop.us. Forum.raspberrypi.com threads on NVMe setups consistently open with ‘are you using the official 27W supply?’ as the first diagnostic.
- The only supply that properly negotiates the 5V/5A custom PD mode the Pi 5 requires for full USB peripheral current delivery
- High efficiency (>91%) with standard PD profiles — also useful as a laptop or phone charger
- Official Raspberry Pi Foundation product; firmware updates for the Pi 5’s PMIC are tested against this supply
- At $12, feels like an underwhelming gift on its own — best bundled with the Pi 5 board or Argon ONE V3 case
- Amazon marketplace has listings mimicking official branding; verify the seller is ‘Raspberry Pi’ or buy from PiShop.us/Adafruit
What to skip
Skip generic electronics starter kits — an intermediate user has LEDs and resistors. Skip generic microSD cards at this stage; the whole point of the NVMe upgrade is moving off microSD for server use. Skip third-party power supplies claiming Pi 5 compatibility — the Pi 5’s power negotiation is specific and only the official supply guarantees correct operation.
The Raspberry Pi 5 board, the Argon ONE V3 M.2 case, and a Kingston NV2 SSD together represent a complete leap forward in capability for any Pi 4 user — faster processing, NVMe boot speed, and proper thermal management in a clean enclosure. Any one of these three alone is a meaningful gift; together they are a complete hardware upgrade.
