The problem is still not resolved. After removing the device printed with "3619" mounted on U4 at JLCPCB and installing "CAP1206-1-SL" purchased from MOUSER, the 6 switches except POWER started working properly. Power is supplied from USB C. However, when I apply 12V to the DC input and press the POWER switch, the board will not start.
The 3.3V regulator I ordered arrived today. I installed it on U2, the Power switch started working properly. At the same time, the second unit was also housed in a new case (blue). When putting it in the case, I replaced the cable between the main and HMI board with a 6cm shorter cable. Now, the assembly is finally complete.
Module 17 Revision 1.0
I was able to assemble the Main PCB and HMI PCB into the case, but the switches on the HMI board do not work properly. Down button -- works as Enter Right button -- works as Up Enter button -- works as Escape Only 3 switches respond, and the other switches, including Power, do not respond.
I assembled a second set, but the situation was the same as the first set. The firmware written to the main board is: v0.3.7-1-g031ecda1d
Since it is not possible to write a callsign, I removed the HMI board, attached the OLED 1.3 inch module used on the previous board (Rev 0.1d/e) to the main board, and was able to set the callsign. . The main board only seems working properly.
