2 × DC Motors (geared) Connectors and Accessories / D-Subminiature Connectors
1 × Case Frequency Control / Crystals
1 × Battery (currently 9v but will switch to rechargeables) currently 9v but will switch to rechargeable Li-Po batteres
2 × Wheels
1 × PCB consisting of:
1 × Atmega328P-PU Microcontroller Standard Arduino MCU. Will be used without bootloader.
1 × L293D H-Bridge for controlling the DC Motors.
1 × NRF24L01+ 2.4 GHz Communications module Using The NRF chip alone might seem cheaper and more efficient, but then we would have to design a more complex PCB and manufacture with better materials than cheap FR4. For now, we will stick to a daughterboard.
1 × Power regulators Subject to change on future versions.
1 × Supporting components including resistors, caps leds and connectors are not mentioned because each version will have a full BOM list published alongside the design files.
