The ClusterCTRL Stack is a power and cooling controller for a stack of five Raspberry Pi.

Splits Power and Data connections from USB-A to micro USB for data + Barrel Jack or micro USB for power. Can be used to access the USB 2 controller on the Raspberry Pi 4 USB-C connection using a USB-A to USB-C cable.

The Cluster A+6 is a side step from the original Cluster HAT and switches Raspberry Pi Zeros out for the more powerful quad core Raspberry Pi 3A+ (can also be used with the older A+ model).

USB to (3.3v) Serial adaptor for use with the Raspberry Pi with a pinout designed to plug straight onto Pi GPIO pins (26 or 40 pin).

Allows four HAT or pHAT (or a mix) to be attached to a single Raspberry Pi 40 way connector.

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 provides a stable 3.3 volts (300 mA max) during reboots.

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.

It can be used to setup additional remote consoles between servers, file transfer, SLIP/PPP networking, heartbeats, etc. Uses USB CDC Serial so drivers are built into modern operating systems (Linux/Windows 10/Mac OS X/Android) so you can just plug and play.

A low cost USB serial Adaptor. Uses USB CDC Serial so drivers are built into modern operating systems (Linux/Windows 10/Mac OS X/Android) so you can just plug and play.

A 12 piece kit of both male/female USB Type-A and Micro USB connectors.

Handheld button and LED board designed for CircuitPython with 4 buttons, 9 LED, SD card socket, 16MB FLASH and Accelerometer.

Solderless USB (CDC) to Serial adapter for the Raspberry Pi Zero (for bare GPIO)

Use a 22pin camera on a full sized Pi, use a 22pin cable to go through a wall, etc.

The Cluster Triple is a step up in CPU and RAM from the Cluster HAT by using Raspberry Pi Compute Modules (CM1/CM3/CM3+).

HAT For the Raspberry Pi - USB Gadget Mode network (+serial) in a compact HAT.

Joins multiple Raspberry Pi camera cables together to extend the cable length (especially useful for the Pi Zero).

Small 6-pin AVR-ISP programmer using the FTDI FT234X and supported by Avrdude with a small addition to arvdude.conf. Can be used to program AVR IC and AVR based Arduino/clone bootloaders using the 6-pin SPI header.

Turns your Raspberry Pi Zero (all versions) into a USB dongle with no soldering

Enables the Raspberry Pi to be used with two HAT/pHAT at the same time.

Power your Raspberry Pi from multiple sources (PSU, Power bank, etc.) with load sharing

Solderless USB to Serial adapter for the Raspberry Pi Zero (for bare GPIO)

Dual Ideal Diode. Power a USB-C device from multiple sources with load sharing

Add a second MMC/SD interface to your Raspberry Pi (Disables WiFi on 3B/3B+ due to them both using the second SDIO interface. Can be used as a Micro SD card reader/writer, additional storage, RAID1/RAID0 root partition)

Dual Ideal Diode. Power devices from multiple sources with load sharing

FTDI 3.3v UART to USB Adapter

Joins multiple Raspberry Pi camera cables together to extend Pi Zero sized cables.

Connect multiple I2C devices without worrying about address conflicts (4 more on the underside). Automatically shows up as an 8 I2C busses. I2C voltage can be set to either 3v3 or 5v with solder bridge.

The ClusterCTRL Single is a low-cost controllable USB Gadget carrier for the Raspberry Pi Compute Module. Breaking out 38 (non-power) GPIO so it's also useful where you need more than the 28 (non-power) GPIO pins accessible on the more regular 40 pin Raspberry Pi (A/B/A+/B+/Zero).

HAT Compliant EEPROM for the Raspberry Pi which can be used to develop HAT, configure your GPIO/load device tree on boot

Power two devices from a single micro USB supply (does not split USB data signals).

Control power to a USB device (on/off) using a switch, or GPIO from a Raspberry Pi, Arduino, etc. (Available in Normally On and Normally Off)

Connect your Raspberry Pi Zero or Pi Zero W[H] directly to peripherals with a Micro USB port such as the Official Raspberry Pi Keyboard.
