This is a multi-functional online writer board that integrates EMMC flying wire, UART serial port, and JTAG functionality for variable frequency air conditioners, compatible with the RT809H programmer.
EMMC Flying Wire Interface: It can directly provide the required 3.3V and 1.8V voltage to the motherboard, making it convenient to power the EMMC during board repairs, thus improving the success rate of EMMC flying wire reading and writing. (Note to correctly select the two voltages for VCCQ)
JTAG Online Interface: It can directly provide power to the air conditioner board, making the online reading and writing of variable frequency air conditioners convenient and quick, eliminating the hassle of chip removal. (Note that the programmer must also be inserted into the programming socket without the chip during online reading and writing)
