This is an all-in-one UPDI programmer with a USB-C port. It can be used to update firmware on flashlights with the 3-pin programming pads such as the Wurkkos TS10 and Sofirn SP10 Pro. This will also work with the NEW Emisar D3AA! You can use either a USB-C to USB-C or USB-A to USB-C cable. Flashing can be performed using AVRDUDE 7 on a computer (use the SerialUPDI programmer option) or by using the ZFlasher AVR app for Android devices. This is an implementation of Serial UPDI communication using a CH340 USB to Serial circuit.
PLEASE READ BEFORE PURCHASING! IMPORTANT INFORMATION REGARDING THE UPDI AND FLASHING THE EMISAR D3AA. WITH THE EMISAR D3AA BEING A NEW MODEL WITH A NEW DRIVER (THEFREEMAN) THE UPDI REFLASHING ADAPTER HAS NOT BEEN 100% TESTED. IT HAS BEEN TESTED TO WORK BUT WILL FAIL SOMETIMES SO YOU WILL NEED TO REFLASH AGAIN IF THERE IS AN ERROR!
