# Raspberry Pi

The Raspberry Pi 4B runs the [python script](/mujoseph-docs/emma-mk1-drsstc/emma-mk1-drsstc-web-controller-software-overview.md) that hosts the web portal for controlling the *Emma Mk1 DRSSTC* over a wireless network. The Raspberry Pi controls the [*Motherboard* PCB via UART](/mujoseph-docs/emma-mk1-drsstc/hardware-overview/electrical-design/pcb-design/motherboard.md#wireless-control-interface).
