Daly Smart BMS UART/BT Pinout
This is the pinout from the Daly SMART BMS side.
The USB-UART dongle that came with the BMS died for unknown reason when the BMS went to sleep/woke up. I damaged a couple other cp2102 based usb-uarts in the same way; Im still unsure why they keep dying, but most likely a high voltage spike on the rx/tx line when the bms wakes up is killing them.
I'm trying an opto isolated usb-uart soon to see if the same problem persists.
