Description
The motor driver can control up to two DC motors at a constant current of 600mAh (1.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes - CW, CCW, short-brake, and stop.
The two motor outputs (A and B) can be separately controlled, the speed of each motor is controlled via a PWM input signal with a frequency up to 5KHz.
The motor and the external power supply interfaces use the XH2.54-2P socket instead of the traditional green screw terminal, easy to use, and you can avoid screwing.
Note: However, when using the board at currents up to 0.6A, it may be necessary to improve thermal performance with a heat-sink.

Description
This is a programmer expansion shield that allows your board to modify the fuse bits and burn bootloader into external chip and other boards.
On-board buzzer and LED indicators, indicating whether the burning is successful, it is convenient for board designers to batch burning for Arduino.
According to OPEN-SMART user manual, it is very easy to use.
Features:
- Compatibility: As it uses SPI pins of ICSP  interface, it's compatible for Arduino.
   It can change to the bootloader burner when it is directly plugged onto the two boards.
- Operating voltage: 5V
- Operating current: 500mA (max)
- board to be burned: support for R3 / Mega2560 / Nano / pro mini (5V 16M)
- On-board buzzer, if the fuse bit is successfully modified, it will sound once, and then if burning bootloader is OK, it will sound once again. If it is not two beeps, burning is failed. You can capture the sound instead of LED lights, so this will improve the efficiency of burning.
- On-board LED indicators, HEART BEAT led lights up like a breathing light when powered normally. During programming, the PROG indicator flashes until it finishes. If the programming is unsuccessful, the ERROR indicator (red) will light.
- Onboard 28P locking seat for Atmega328P, Atmega168P, Atmega8 bootloader burning
- Onboard ISP_6PIN interface, for the external board bootloader burning for Arduino.
- On-board ISP_10PIN interface
- On-board FT232RL and CH340G USB to TTL programmer interface for uploading code to the chip on the 28P locking seat.
