Know before you buy
The board is designed to work with both hall-effect and optical encoders. It features solder jumpers that allow you to easily configure the pull-up resistors to match your specific encoder type.
Yes, while it is optimized for those specific gear motors, it will work with any motor equipped with a quadrature or pulse/direction encoder that falls within the board's operating voltage and signal requirements.
The board operates on a voltage range of 3V to 5V. While it functions at 3V, we recommend using 5V to ensure optimal performance from the onboard 40MHz oscillator.
The board utilizes an SPI interface, which allows for fast and reliable communication with most standard microcontrollers. This setup enables you to easily track motor position, speed, and distance using the 32-bit counter.
Yes, the board comes with the 1k pull-up resistors pre-set for hall-effect encoders. If your project requires a different configuration, you can adjust these using the onboard solder jumpers.
A 32-bit counter provides a very large range for tracking pulses, which is essential for maintaining high precision in position and distance measurements without the risk of the counter overflowing during long operations.
