MMDVM Hardware

Hotspot are a combination of a Raspbery Pi and MMDVM Board in Cooperation

Both the RPi and STM32 are ARM based SOC's cummunicating via a Serial Interface

Raspberry Pi's:

• The Raspberry Pi Zero and Zero W use the Broadcom BCM2835 SoC
• The Raspberry Pi Zero W 2 uses the RP3A0-AU CPU, a 1 GHz 64 bit ARM Cortex A53, on 512MB of SDRAM.
