HATs, audio boards, camera adapters, power accessories and microcontroller modules for Raspberry Pi projects. This category includes both add-ons for Raspberry Pi computers and boards built around RP2040 and RP2350 microcontrollers.

The RP2350 Stamp XL is a hand-solderable module with 16 MB of flash, a voltage regulator, a LiPo charger and access to all GPIO pins. For something a bit different, pico2-ice combines an RP2350B with a Lattice iCE40UP5K FPGA and PMOD interfaces, with support for open-source toolchains.

The Bidirectional USB 3 Multiplexer lets you share a device between two hosts, or switch between two devices on one host. Louder Raspberry Hat Plus adds a TAS5825M DAC with built-in DSP for audio projects. Four quite different boards, depending on what you're working on.
