Hello,

Have got Realacc R11 mini drone, would like to pair it with my DEVO 7E, any ideas which protocol used?

UPD transmitter based on MX5323 chip



MX5323 is a low-cost, highly integrated 2.4G wireless transceiver chip that uses GFSK modulation. chip Integrated RF transceiver, data link and low power MCU. The user issues instructions to the chip through the I/O port of the MCU Order, the chip automatically completes the transceiver configuration to communicate, and automatically determines whether the data transmission/reception is successful according to the response information Power, so as to retransmit, lose packets, continue to send and wait for operations, simplifying the user program. Transmitter support power Adjustable, the receiver adopts superheterodyne structure, the peripheral circuit is simple, only a few peripheral passive devices are needed. The chip uses SOP16L The package of the pin conforms to the RoHS standard.characteristic● 2.4GHz general ISM band operation;● Single chip completes sending and receiving;● Support 10 I/O port communication:● I/O port supports sleep wake-up function;● Support automatic data packet processing;● Support 33mm wire antenna;● Support single panel;● Support pin function customization;● Built-in 6 data channels, support self-organizing network;● 2.5V~3.6V power supply;● MCU memory FLASH: 2K bytes RAM: 208 bytes (40 dedicated RAM + 168 general RAM)● MCU features AD detection, PWM output, built-in up/down resistance, key wake up
