EEVblog #1144 – Padauk Programmer Reverse Engineering
David looks at the pins on the Padauk PMS150 programmer for potential reverse engineering.
TLDR; It doesn’t look easy to reverse engineer this protocol, it’s messy with lots of voltage levels, as Padauk said it would be.
Just buy the programmer for now!
There is also a Flash/EEPROM re-programmable version of the chip, the PFS154C.
