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.
Note: some been having issues reflashing the firmware, please make sure you use a short OTG cable not the 1M length cable
REFLASHING THE EMISAR D3AA
SERIALUPDI is the programmer
AVR32DD20 is the MCU (D3AA)
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!
