Hello,
according to the Espressif website the above mentioned 'ESP32-WROOM-32U' is not recommended for ned designs. Instead we should use the 'ESP32-WROOM-32UE' modules.
Unlike the old modules ( https://www.espressif.com/sites/default ... ficate.pdf ), I'm unable to find a certificate for Japan for the new module.
Could you please provide a link for the new certificate?
Best regards,
Jochen Loeser
