2.1.1
BLE UNO R3 Master Control Board
In " Hummer-Bot ", we used the
BLE-UNO R3
as the main control board, which has 14 digital input/output
pins (6 of which can be used as PWM output), 6 analog inputs, and a 16 MHz ceramic resonator, 1 USB
connection, 1 power socket, 1 ICSP head and 1 reset button. It contains everything that supports the
microcontroller; You just need to connect it to a computer via a USB cable or start with an AC-DC adapter
or battery.
