I-Racer Teardown

1. 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.
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
2.  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
   LDO: CYT6206
   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.

3.  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.
