JRC Board

Description

JRC board is a microcontroller board based on the
ESP-WROOM-32. It has 20 digital input/output pins
of which pin 25 and 26 can be used as analog
outputs, 12 analog inputs, an USB type 3 connection,
an ICSP header and a reset button. It contains
everything needed to support the microcontroller. Simply
connect it to a computer with a USB cable or battery
to get started. Keep Up with the World A Low-Cost
Board for Schools in Bangladesh and Beyond. Powerful
System on Chip. An In-House Development Board for
our future products to blend in the Existing Ecosystem.
