Custom ESP32 PCB Soldering

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