Introducing the R21, an advanced industrial general-purpose solution designed to enhance the capabilities of the Raspberry
Pi Zero. By seamlessly integrating the Pi Zero and its 40-pin GPIO header onto the carrier board, the R21 provides a robust foundation for expanded functionality.

Unlocking new possibilities, the R21 features a PCIe-based M.2 Key M slot, offering reliable and high-speed solid-state storage to elevate the performance of the Pi Zero. Powering the R21 is a breeze, thanks to compatibility with an 8-18V DC power supply equipped with a barrel jack connector, or the optional Power over Ethernet (PoE) PD.

The R21 redirects the Pi Zero’s USB ports, which should not be used independently. These ports are linked to the board, serving distinct functions. Additionally, specific pins from the 40-pin header are allocated for proprietary functions. This rerouting is achieved through solder contacts beneath the Pi Zero.

In this version the CSI port is not accessible as it is blocked by the PoE module.
