SparkFun ROB-15451 - part of the Qwiic ecosystem .
Qwiic system - what is it?
Qwiic Connect by SparkFun is an ecosystem of sensors based on the I2C communication bus, actuators, and cables with dedicated plugs. This solution simplifies the prototyping process. All boards supporting Qwiic use a common, 4-pin JST connector with a spacing of 1 mm. This reduces the amount of space required on the PCB, and polarized connectors cannot be misconnected.
The output of the module
The module has outputs in the form of two Qwiic connectors and screw connections (double and quadruple) located on the opposite edges of the board:
- VIN (MAX 11 V) - power supply for engines +
- GND - system ground -
- A1 - (type: O) connection # 1 of motor A
- A2 - (type: O) connection 2 of the A motor
- B1 - (type: O) connection no.1 motor D
- B2 - (type: O) connection no.2 motor D
