- 【USB Type C Port Reinforced】-This is latest the USB type C port reinforced and make it more stronger solder points.
- 【 microcontroller】-The ProMicro is similar to the Pro Mini. The USB type C transceiver inside the 32U4 allows us to add type C connectivity on-board and do away with bulky external type C interface.
- 【Multi-channels】-This tiny little board does all of the neat tricks that you're familiar with: 9 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere.
- 【Voltage regulator】-There is a voltage regulator on board so it can accept voltage up to 9V DC.The maximum voltage allowed on the RAW pin is 9V, 6-7V input recommended. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC.
- 【Anti-ESD Package】The boards came in a box package with a pinout diagram printed on, each in their own anti-ESD(Electronic Static Discharge) bag with 3 rows of header pins.
