1 × Arduino Nano with Atmel 328p (£4) I had issues compiling the nrf9000 library to run on the Atmel128
1 × Dual DC motor driver based on the TB6612FNG (£4) (https://www.google.com/search?tbm=shop&hl=en-GB&source=hp&biw=&bih=&q=tb6612fng)
1 × nrf8001 BLE module with SPI connectivitiy (£11) (https://www.google.com/search?tbm=shop&hl=en-GB&source=hp&biw=&bih=&q=nrf8001)
1 × "Smart car kit" robot platform (base, motors, wheels, battery holder) (£9) These can be found on Ebay and from a number of sources
1 × Raspberry PI 4 (£34) + Raspbian SD card (£6) Ideally I'd use a Raspberry Pi Zero W and add a USB BLE dongle but so far I stick to the RPi 4 that features Wi-Fi+BLE
1 × USB power bank (£12) The RPI is powered separately from the car, I haven't measured autonomy, a measurement I did a couple of years ago suggested that a Poundland £1 powerbank could sustain a RPi Zero W doing video streaming for 2 hours.
1 × Raspberry Pi wide angle lens camera (£15) Any other camera will do but FPV works better with a wide FOV
