Size: 84mm x 44mm with 2mm mounting holes
Processor: ESP32 on ESP32-WROOM-E module with WiFi and BT V4.2
Power Input: 12v @ 12 amps max via 5.5mm x 2.1/2.5mm barrel connector or 5v via USB-C connector.
12 amp resettable fused input power.
On Board Regulation: 5v @ 2 amps switching regulator, 3.3v @ 1.0 amp.
Input/Output: One 5v tolerant input (1k pullup) and one 5v driven output, with 12V power (7+ amps per conn.) and ground on four, four-pin Molex KK series connectors. Compatible with most PWM PC style fans with speed return. Of course other use cases for these interfaces such as driving LED strings are available.
I/O: Three screw down three position headers with common one-wire interface as well as 3.3v power and ground.
I/O: USB 2.0 via USB-C connector using the CP2102N.
I/O: Standard WEMOS daughter interface on two 1x8 pin headers.
I/O: JST SH conn w/ I2C interface 3.3v/5.0v selectable power (compatible with Adafruit's STEMMA QT/ Sparkfun Qwiic sensors).
