| 2025-01-28 | pcb: D3: Connect directly to 3V3 and add TODO | xengineering | |
| In general the PWR LED D3 should be connected directly to 3V3. Nevertheless there should be the option to implement a night mode by firmware which turns of the LED. | |||

| 2025-01-23 | pcb: U2: Fix datasheet URL | xengineering | |
| 2025-01-20 | pcb: Remove note about MAC EEPROM | xengineering | |
| It could be validated that the ESP32 S2 has an embedded hardware MAC address and it is assumed that this is the case for the S3 too. | |||

| 2025-01-19 | pcb: SW1-SW2: Select exact part and change footprint | xengineering | |
| 2025-01-19 | pcb: R1-R3: Select resistances | xengineering | |
| These are selected so that the relative intensities of D1-D3 is 50 %. | |||
| 2025-01-19 | pcb: Remove unnecessary space from one MPN | xengineering | |
| 2025-01-19 | pcb: R4-R5: Finish part selection and add datasheet | xengineering | |
| 2025-01-19 | pcb: J3: Remove wrong datasheet reference | xengineering | |
| 2025-01-19 | pcb: J1: Select JTAG connector without pin 7 | xengineering | |
| It seems that pin 7 (KEY) is always not connected and used with some cables to block wrong-oriented connections with plastic at this point. The ARM documentation [1] sadly is not very clear about this. To be mechanically compatible with all cables the cortex debug connector without pin 7 is selected by this commit.

| 2025-01-18 | pcb: Make part choice for J1 (JTAG) | xengineering | |
| 2025-01-18 | pcb: Do not populate J3 WAGO connector | xengineering | |
| This is currently the only THT part. It can be soldered easily by hand so it is for now excluded to make production cheaper. | |||
| 2025-01-18 | pcb: Add J3 WAGO connector from Ultra Librarian | xengineering | |
| The actual files are not committed because of licensing concerns. Will be replaced soon by self-developed symbol and footprint. | |||
