Thus the custom PCB with the STM32WL MCU does not make sense anymore. To get started the Ethernet variant will use a ST NUCLEO board to avoid creating a custom PCB first. pcb: Add TLV70233 voltage converter 2024-06-08T13:49:59Z xengineering me@xengineering.eu 2024-06-08T13:49:59Z urn:sha1:63b35a95cf6f29b867e27f9bb99fa03a4b5c4fa3 This IC has a small footprint and will provide the 3.3 V for the microcontroller. pcb: Split into a hierarchy of schematics 2024-06-05T19:38:47Z xengineering me@xengineering.eu 2024-06-05T19:38:47Z urn:sha1:2b38114643b68670092d6c389c51a0ae01d50e04 pcb: Add 10-pin ARM Cortex debug connector 2024-06-05T19:20:48Z xengineering me@xengineering.eu 2024-06-05T19:20:22Z urn:sha1:ba97734a2cbfff1b73581fd275bbd26583fdda89 pcb: Add USB-C connector to schematic 2024-06-05T19:09:50Z xengineering me@xengineering.eu 2024-06-05T19:08:22Z urn:sha1:0bcd66f32c6fcd24b01fc87b0d02c9ac4431b938 pcb: Add STM32WL55JCIx microcontroller 2024-06-03T19:04:28Z xengineering me@xengineering.eu 2024-06-03T19:04:28Z urn:sha1:11cb5dc9e86a92314d78999674fe675ea3d52b78 Based on UM2592 the development kit Nucleo WL55JC which is used for firmware development is based on the STM32WL55JCI7 microcontroller. Thus this MCU should be a good starting point for now. pcb: Create empty KiCad 8.0 project 2024-06-03T18:45:41Z xengineering me@xengineering.eu 2024-06-03T18:45:21Z urn:sha1:6053827028a6590196baea8a3928fa10c1f2ddc6
