| May 19, 2023 at 20:38 | comment | added | Bruce Abbott | "The IC receives a constant 12 V" - What is the power supply voltage? Could the diode between pins 1 and 8 be a Zener? What value and voltage rating is the capacitor? | |
| May 19, 2023 at 20:36 | comment | added | Jim Fischer | It could be a Microchip PIC part or a Picaxe part (e.g., picaxe.com/hardware/picaxe-chips/picaxe-08m2-microcontroller), or "other". | |
