Universal control boards

Pigeon One control board

I/O capabilities:

GPIO1 – 10way header and pluggable screw terminals - 8 logic inputs/outputs (6 with A to D) allow connection of switches, buttons, etc;

GPIO2 – 10way header – 8 general purpose inputs/outputs arranged as an 8-way buss

GPIO2-Buffered – 10way header and pluggable screw terminals  - 8 driven outputs allow direct powering of LEDs, relays etc up to 0.5A per channel (2A total for all channels) and selectable as 5V or Board Supply Voltage (DC in) in groups of 4.

GPIO3 – 10way header - 8 additional general purpose input/outputs, also connects to Baby Pigeon modules

GPIO4 – 10way header – 8 additional general purpose input/outputs, also connects to Baby Pigeon modules for Network provision.

Serial – 10way header – contains SPI, I2C and RS232 connections, also connects to Baby Pigeon modules. (note RS232 is jumper selectable between two pins on GPIO1(losing 2x A to D), two pins on GPIO3 or not connected)

Power – 10way header – contains Vin, 5V, GND, Reset, and RS485

RS485 serial data link for linking 16+ boards off a 4-core cable up to 200m (link also provides power) or DMX512
