It’s not possible to enter manufacturing for the ESP32-M1 design with the TI part due to the part shortage issue and with the price hike. A suitable replacement for this chip was found, after some search, from Analog Devices.
The technical parameters are similar to the TI part, but not the footprint. Analog Device parts are purchased and soldered to the current PCB board with some modifications, as the footprint is different. The design has been tested for crucial parameters and has the same performance as the TI part. Please see the new design at https://github.com/bisonscience/ESP32-M1-Reach-Out/tree/main/Hardware%20Design/ESP32-M1%20AD%20LDO
The new PCB with Analog Devices footprint is currently being ordered for further testing. If in between the TI part comes available, the manufacturing will go with the TI part.
