Modify the CH341A EEPROM Programmer (Black Edition) for 5V 93XXX & 95XXX Automotive Use

In this video I'll go over a combination of programmer software, EEPROM adapter, and programmer printed circuit board (PCB) modifications to allow +5V 93XXX (e.g., 93C66) and +5V 95XXX (e.g., 95040) SOIC8 / SO8 EEPROMs to also be supported by the ubiquitous CH341A USB MinProgrammer (Black Edition), in addition to its usual SO8 24XXX and 25XXX device support, but now in +5V as well (e.g., 24C08). With this support you can use this programmer to change VIN information in most Radio or Body Control Module (BCM) types sold in the USA from the 1990s and early to mid 2000s, as well as to perform odometer mileage correction manually in these same BCMs or an instrument cluster, for example. In order to reliably write some SO8 EEPROM devices encountered in automotive circuits a +5VDC supply and programming voltage, rather than the default +3.3VDC, is required. This particular inexpensive programmer can be easily modified for this automotive module voltage requirement and allow for doubling the number of supported devices in doing so as well (from 2 to 4 EEPROM families) as shown in this video. While not all SO8 EEPROM devices can be written, or even read, in-circuit of automotive module circuit designs many can, and for those that cannot this programmer can still provide a very inexpensive DIY solution for light duty repair projects off circuit as well. These inexpensive programmers lack the over current protection or pin protection of most general purpose programmers, which...
