In my last post, I talked about the tests I did with the AMS1117 Board. Now it’s over to the ATmega328p Breakout Board. The testing was a lot simpler, and included the AMS1117 board.This was it. The test was just to run a sketch on the ATmega328 microcontroller, uploaded using an Arduino Uno. The sketch was some patterns that used all 17 outputs (the 11 (not using RX or TX), plus the analog in pins used as digital outputs). The chasing patterns made sure that that the pads were connected in order. Here’s a video:
I used my multimeter to do some other tests. I tested the other pads on the board (RX/0, TX/1, and the Vcc and GND pads) with the multimeter. I also measured the curent flowing between the AMS1117 and the ATmega328 board. The reading in the picture above is from when all of the LEDs are on.
One thing I realized is that the 1A fuse for the uA and mA setting on my multimeter is blown. I went looking for them and the cheapest I can find is a 20 pack for ~$5… The A setting works just fine so I can live with it. The fuse on the A setting is 10A so it should last a while and would be the one I’m more willing to replace if it does blow someday.
Anyways, thanks for reading! I’m still planning out some projects so stay tuned!
