- Dimension: 60×85mm.
- Power supply: 5V @500mA.
- Communications include I2C, UART, and SPI.
- Testing directly output function on board via blinking TEST LED.
2.MCU
In Circuit Serial Programming (ICSP) is connected to MCU via 7-Position Side Switches to isolate computer and circuit when It operates.
You can reset board by using reset button. A interruption is created when you push the SW4 button. This event can be used to reset EEPROM or interruptive function in your project.
PIC16F877A is installed on 40-position socket. This socket helps installation and uninstallation the ICs faster.
3.Communications
The PIC16F877A MCU supports the serveral serial communicationas including UART (Universal Asynchronous Receiver-Transmitter), SPI (Serial Peripheral Interface), I2C (Inter-Integrated Circuit).
