- Topic: DFR0116 - USBtiny ISPYou Reply: UPDATE: I made a mistake during the 6pin vs 10pin test. I should've use the v1.0 schematic. Pin 1 6pin miso beeped when connected to pin 1 10pin miso which is wrong and should be mosi. Then my board is v1.0. Well luckily i rarely use 10pin. If i need to maybe i can use jumpers or crimp a corrected cable instead.
- Topic: DFR0116 - USBtiny ISPYou Reply: I did the continuity testing (using the corrected v.1.1 schematic) from the chip (attiny 2313 pin 17 mosi) to the pin 1 mosi (10pin) but no beep. Tested also for miso. Then repeat the test using v1.0 schematic also no beep. I think the buffer chip is in the way. Then i tested the 6pin against 10pin and i get the beep. If 6pin is correct and the 10pin must also be correct right?

- You Reply: Thanks for the info. So the 8 pin headers are extra 5v/3.3v and GND. Tried looking for any jumper to select 5v/3.3v but found none on the board but there is a marking on one side 5v and the other side 3.3v. maybe the board supply both voltages simultaneously but on opposite side.
