F.A.Q – AstroCAN BD-1 Logics

What is it?

The AstroCan BD1-Logics board is designed for Michael Baddeleys BD-1. It fits the head and is controlled via a piggyback Arduino Pro mini or via any other microcontroller. It has 251 3535 RGB Leds.

Features

  • ESP-NOW Wireless Dome/Head<->Body Comm (serial, Canbus, I2C)
  • CAN-Bus ready software for upcoming CAN-enabled Astromech Devices

The ESPNow system is exclusively utilized for connecting the body/head and dome. It efficiently transfers all CAN signals and one serial interface between the dome/head and body through ESPNow.
