OPEN-SMART R3 DIY Module Built in Bootloader Compatible for Arduino
– It has been burned bootloader compatible for Arduino.
– It uses a locking seat, so it is easy to replace the chip.
– You can use FT232 USB to TTL module, CH340G module, to burn the program. The USB port onboard is only for supplying power but not uploading code.
– The program, expansion shields, development environment IDE is compatible for Arduino.
– Microcontrollers: ATmega328P-PU
– Operating voltage: 5V
– IO interface logic voltage: 5V
– Operating Current: 500mA (max)
– Digital I / O pins: 14 (of which 6 can provide PWM output)
– Analog input pins: 6
– Clock frequency: 16MHz
– On-board test indicator LED, and the beginners can program to control it.
– Onboard power indicator.
– Bootloader burning Interface: ICSP
– Programming Interface: GND, 5V, RX, TX, DTR
Can upload codes by CH340G Debugger (link):
