Overview
The Pi2Go Mk2 is the evolution of the very popular original Pi2Go, first shipped in April 2015. The major changes are:
- Improved assembly method, particularly the motor mounts
- No wires for attaching the battery packs
- Better quality wheels with high grip tyres
- Wheel sensors built into both wheels
- Programmatic access to the raw battery voltage
- Improved analog light sensors – one in each corner
- 10 individually addressable Smart RGB LEDs
- 2 edge connectors compatible with Pimoroni’s Breakout Garden with full access to I2C signals and individual GPIO signals
- Improved motor controller allowing higher speeds and optional braking on stop
- Now with 4WD option
Specification
- Requires 6 x AA rechargeable battery cells (not included)
- Supports all versions of 40-pin Raspberry Pi
(NB. the Raspberry Pi 4 consumes a lot of power and it is recommended to use one of the optional 7 x AA, or 2 x 18650 battery boards) - Motor controller: DRV8833
- Analog input (light sensors and battery) MCP3008
- Switching 5V power supply using TPS5430
- 10 x SK6812-3535 Smart RGB LEDs (compatible with neopixels) – on battery board
- On/Off switch with Blue indicator LED – on battery board
- 2 x TCRT5000 infra-red obstacle sensors (front corners)
- 4 x SFH3710 light sensors (all 4 corners)
- 2 x TCRT5000 infra-red line follower sensors
- 6mm tact switch for programmatic use
- 4 x servo connections – direct from GPIO pins, with 5V and Gnd signals
- 2 x optical wheel sensors with 20 slot encoder wheels (ie. 20 pulses per revolution)
- 2 slots for breakout boards, including ultrasonic distance sensor and IP Display. These slots are compatible with Pimoroni’s Breakout Garden range.
- Overall size with wheels attached: 148 x 118 x 98mm (length x width x height)
- Weight (excluding Raspberry Pi & batteries): 282g
