Re: R31 resistor popped off the PCB

I've tested what you mention under both options above (original and modified files) and unfortunately it doesn't look like anything serial is working :? I'm all out of thoughts on this one to be honest.. I can't figure out the schematics either to understand where the serial send/receive pins go on ...

Re: R31 resistor popped off the PCB

Hi obcd, The printer is the following from Adafruit: http://adafruit.com/products/597 . Quote from the product page: "you simply need a 3.3V-5V TTL serial output from your microcontroller". I reverted settings the instructions had called for to free up the serial port for software use (editing initt...

Re: R31 resistor popped off the PCB

Thanks for the info. The resistor does look slightly warped, perhaps that confirms heat was an issue. I tried going over the schematics to understand where the serial TXD GPIO pin goes to in an effort to see if there is any physical damage (at least visually) but that is a bit beyond my understandin...

R31 resistor popped off the PCB

Hi everyone, A thermal printer I had connected to serial TXD and GND stopped working all of a sudden, so after a few hours of pulling my hair out I spotted this on the back of the PCB (rev1 board): R31_pcb_rev1.jpg I'm not too knowledgeable with the electrical aspect of things, but I spotted this on...
