  • DAGU robot MINI DC gearbox DG01D 48:1
  • Lithium Poli Battery 3.7V 1300mAh
  • Qwiic motor driver (1.5 A peak drive per channel, 1.2 A steady state, Operates from 3 to 11 Volts with 12V absolute max, 3.3V default VCC and logic, Controllable by I2C or TTL UART signals) based on DRV8835. Similar chip I reveiwed already
  • Pi Servo Hat. 16 PWM channels, controllable over I2C
  • Accelerometer and gyroscope. I2C, 3.3V operating voltage
  • Passive Infrared (PIR) sensors are great for detecting motion in a small area around the sensor.
  • MicroMod MikroBUS Carrier Board - I also mention it in my power board development notes. equipped with a MCP73831 Single-Cell Lithium-Ion/Lithium-Polymer Charge IC. It receives power from the USB connection and can source up to 450mA to charge an attached battery. Plus 3.3V 1A Voltage
