Technical Description
The Equipment Under Test (EUT), is a portable 2.4GHz Transmitter (Robot Unit)
for a RC Robot. The sample supplied operated on 40 channels of BT 4.2 BLE
only, normally at 2402 - 2480 MHz. The channels are separated with 2 MHz
spacing.

The EUT is powered by 6.4V rechargeable battery or 6.0V (4 x 1.5V “AA”
batteries). After switch on the EUT, the car will be moved forward or backward
and turned left and right based on the switches pressed in the phone application
controller.

The brief circuit description is listed as below:

1. U4 acts as Bluetooth Module
2. U3 acts as MCU
3. Q1, Q2, Q4 & Q5 and related components act as Motor drive of M1
4. Q16, Q17, Q19 & Q20 and related components act as Motor drive of
M2
5. U1 acts as voltage regulator
6. Y1 acts as Crystal Osc. o1. U4 acts as Bluetooth Module
