4.7.2023 While initial flashing, 7/100 broke (bare PCB)
24.7.2023 While EOL testing for ...

ESP32-C3 damaged through production (ESD?)
Hallo
In ower new Project we use the ESP32-C3 on a small PCB to sample a I2C sensor.
Now on our first Prototype series we observed quite a big number of broken devices (12/100pcs.). We suspect ESD but we are not sure. The PCBs were professionally build unter ESD save surrounding. The programming ...
