A board I designed in June 2025 that is a digital signal processing project with the SGTL5000 and ESP32S3.
Connect SPI TFT
- RST ->
- CS ->
- DC ->
- SDA -> D41 MOSI
- SCL -> D40 CLK
- GND -> GND
- VCC -> 3V3
V0.1 - Known errors
- The IBOM is not correctly generated
- IDs
- 100nf
- Last U5 U4
- IPN
- Missing power on LED
- USB Digital connections are flipped
- The logic of L2 is working, but seems that the resistor or the orientation of the resistor is wrong. It gives 5V when charging.
- Change vias so they are not exposed
- Move vias that are close to pads
- It is necessary to put the battery to work
- Put zenner diode and connect Vbus to ldo
- Put (cheap) castelated pins
- The holes for the screws are not made to have a battery
- SPI connections put the correct silkscreen
- Make the pcb wider and shorter, maybe by removing components silkscreen or moving the sd to the bottom layer. That would be nice but is not necessary.
