Pi4, ClusterHAT, FanSHIM, etc. NOT included. Keep the 3.3v rail alive between reboots. When rebooting a Raspberry Pi 4 the 3.3 volt rail is reset which causes problems for some HATs. 3v3 Sustain fits in between a Raspberry Pi and a HAT/pHAT and...

What is it? APlusCam is designed in the shape of a Raspberry Pi HAT with mounting holes for a Raspberry Pi Camera and suction cups allowing the camera can look out through a window. The original version of this was a PCB, but I've now updated it to...

The ClusterCTRL Stack (controller and passive backplane) is a simple way to both power and control cooling for a stack of 5 Raspberry Pi. Controller Powered by 12-24V PSU. 20 pin header for Power (2x5V and 2xGND for each Pi). 6 pin header for...

The I2C multiplexer allows connecting multiple I2C devices with the same address onto a single I2C bus (PCB colour may vary). For each multiplexed output there are 4 pins - data ports SDAx, SCLx GND ground and V for power. The "V" output can be altered...

Dual Supply for Raspberry Pi (A+/B+/2B/3B/3B+) Power from each Micro USB connector goes via a MOSFET "Ideal Diode" which is then connected directly to the Micro USB socket on the Raspberry Pi. Data pins are not connected from either Micro USB port (as...

Allows two HAT or pHAT (or a mix) to be attached to a single Raspberry Pi 40 way connector. All pins are connected *except* ID_SD and ID_SC (HAT EEPROM) which have solder jumpers – this allows HAT which follow the specification correctly...

Cluster Hat Version 2.5 The Cluster HAT is also available in a Cluster Kit (comes with 4 Raspberry Pi Zero W) The cluster HAT is physically compatible with the Raspberry Pi Zero 2, but the Zero 2 can consume up to 1.1A, it is not known yet how many Pi...
