[0:00] Hello YouTube! We’ve received a box from jail PCB it’s our moon lamp custom
[0:08] circuit board partially assembled with SMT mounted components
[0:14] On the board, we have the linear regulator to take our voltage from 5v
[0:20] down to 3.3v We have our output drivers hooked up to the PWM signal
[0:26] from the ESB 32 and connect it through to the 5v supply and we have some
[0:32] indicator LEDs for RX, TX, 5v and 3.3v. So let’s get the ESP32
[0:41] soldered on so I’ve aligned the ESP to the position on the PCB where it
[0:50] should go and I’ve taped it down. I’m going to connect a few of the pins just
[0:55] to hold it in place and then once we’ve got some of the pins soldered in we can
[1:01] remove the tape and solder in the rest of the pins. There is going to have to
[1:07] be some cleanup of the joints where we’ve got bridged joints so I’ll use my
[1:13] solder sucker to clean those up a bit later
[1:17] so we’re carrying on soldering obviously this is highly speeded up I didn’t think
[1:23] he wanted to watch the full long process of the soldering so we carry on
[1:32] soldering up ESP 32 now some of the pins are quite tricky to solder things
[1:41] let the ground pins and the 3.3-volt pins are quite hard. We have quite a
[1:48] large ground plane so ground pins can be quite hard to solder and the 3.3 volt in
[1:55] has quite a thick track so I’ll bring in my bigger solder bit later to
[2:02] actually sort of those. Just touching up some of these solder joints and now
[2:12] we’ll use our solder sucker to clean up some of the bridged joints. Need to clean
[2:22] off all the flux with a bit of alcohol
[2:31] and now I’ll just touch up some of these joints with the bigger solder land
[3:07] That’s the ESP32 soldered up I’ve started on the header pins and I’m just
[3:13] soldiering in the last components which are the screw terminals. So that’s our
[3:20] board all soldered up. I’ll give it a quick clean to remove any flux
[3:26] residue and now we can move on to actually testing it. So what I’ll do is
[3:32] I’ll wire up my USB to UART board and we’ll download the simple blink sketch,
[3:42] hit the program button and we should see the TX LED start to flash. Here we go
[3:53] the program is downloading and now we just need to disconnect the programming
[4:00] pin from ground and hopefully we should see a blinking LED. So our board seems to
[4:08] work it’s not best soldering job but we seem to have our joints ok and it’s working
[4:15] So I’ll download the prototype software for the moon lamp
[4:21] and let’s wire up the LED and see if it works. I’m using the web interface for
[4:30] the board so let’s see if I can control the LEDs. This is the red Channel
[4:44] . The green channel should come on and now the blue channel. Looks like our board
[4:55] is fully functional and seems to be working as designed. I hope you enjoyed
[5:03] this video it was a bit of a blast through my custom ESP 32 board. There
[5:09] are detailed videos of the design process and PCB manufacturing in the
[5:15] channel. I’ll put links in the description. I hope you enjoyed this
[5:19] short video and if you did please hit the subscribe button and hit the bell as
[5:25] well so you know where new videos are released.
[5:28] Thanks for watching and I’ll see you in the next video
