This datasheft adjacent to pin 1 and pin In your photo you will see a corresponding dot in the IC in the left lower corner, plus a white dot on the pCB. Both indicate pin 1.

The dot or indent on the IC, or sometimes a truncated corner on the package, is a common way of indicating wherepin 1 is. A method datasheef this outyourself would be to use a continuity tester with beeper, as found in many multimeters, or a meter set to low ohms, place one probe to PCB ground and then run the other probe along the IC pins to find the ground connections.

Note that when using a continuity tester or low ohms range the meter’s inter- probe open circuit voltage MAY exceed the IC’s absolute maximum voltage rating – eg it may be at 9V depending in the meter. This is extremely unlikely to cause damage in such cases BUT if it datasheef you would be responsible.

Some multimeters use two or three x AA batteries and have a correspondingly lower inter probe voltage. If you have a 9V meter and really care about the probe voltage you could use a zener diode or resistor to load it down somewhat and then note what happens when you short the probes to eg ground.

I found the schematic of the board here. For example, there are two GND pins on each connector: The first pin of any connector is marked with an white square on the board.

The 1 pin of the microcontroller is marked with the white dot on the board, just beside the pin. By clicking “Post Your Answer”, you datasjeet that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.
