Is there any Programmer for M66 module

how can we program on-board soldered Quectel M66 module. Is there any programmer which can program externally using UART.

Hi Akshay
Thanks for your query…!
You can program the M66 module on board using TX, RX(main UART) pin of the module.
for that you need only USB to TTL or USB to serial cable(if your board having MAX232).
Using Qflash tool you can program the M66 module.
please find the below link to download the Qflash tool.

You will also find the User guide for Qflash in same downloaded folder please refer the same.
