@Bibbbi It seems the touch pins are not connected. Have you adapted the software to use buttons instead?
It would be really nice if you could provide a BOM (or simply post a list of the components here) because otherwise this PCB is not very useful.

@pastaclub The touch pins are connected. The hardware buttons are optional, if you use a display without touch function.

BOM List:

	Value	Case
C1, C2, C3, C4, C6	100nF	SMD-0805
C5	47uF 25V	SMD-D 7343
D1, D2, D3, D4, D5	MBR120VLSFT1G	SOD-123FL
J1	DC-005	DC Power Jack 5.5x2.1mm barrel type
R1, R2, R3, R4	1K2 Resistor	SMD-0805
R5, R6, R7	10K Resistor	SMD-0805 (optional)
T1, T2, T3, T4	MMBT2222A NPN	SOT-23
X1	KF301-4P	Terminal Red 5,08mm
X2	KF301-8P	Terminal Blue 5,08mm

Thank you! I ordered the transistors and terminals (I had compatible components for the rest). I will get the PCB made and see how it works for me. Maybe that also fixes my problem with the sensor.

We could add the schematics and board files to the repository if you want to share them.

According to the schematics and PCB, IRQ and CS pins on touchscreen are not connected anywhere, how can it work?
