Remote Control Receiver Module - Keywish Hummer-Bot Instruction Manual

Fig.3.2.40 Remote Control Receiver Module
There are 9 interfaces at the end of the receiving head, each of which is shown in the following table:
1 2 3 4 5 6 7 8 9
DI/DAT DO/CMD NC GND VDD CS/SEL CLK NC ACK
Note: The appearance of the receiver will be different due to different batches, some with a power light, some
without, but the use and definition of the pins are the same.
DI/DAT: The signal flows from the handle to the host. This signal is a serial 8-bit data which is transmitted
synchronously to the falling edge of the clock. The read of the signal is completed in the process of clock
changing from high to low;
DO/CMD: The signal flows from the host to the handle. The signal is similar to the DI, a serial 8-bit data,
which is transmitted synchronously to the falling edge of the clock;
NC: Empty port; .
GND: Ground;
VDD: The 3~5V power supply;
CS/SEL: Providing trigger signals for handles, the level is low during communication;
CLK: The clock signal is sent by the host to maintain data synchronization;
NC: Empty port;
