- Quick overview of the I-Racer HardwareI purchased I-Racer to start my RC car project, and it is a nice starter kit that supports Android apps to remotely control the car via Bluetooth.
- Hardware components
These are the major parts list that I-Racer is probably using.
Some parts were hard to guess by checking the marking on the chip.
MCU: ATMEL ATMEGA48-10AU
Battery: ATL462849, 490mAh, 150mOhm, L 48mm x W 28.2mm x H 4.3mm
Bluetooth Module: SKU80711
I found a good website that is also investigating the I-Racer hardware.
- Motor driver circuit
After the circuit investigation, I created a clone of the motor driver circuit.
I am not 100% sure this is exactly same as the one on the board though...
Next step is to simulate this circuit using SPICE.
