Re: Using ESP32 WROOM modules outdoors in sunlight, temperature margin

Hello WI, you will have to take care of heat dissipation beyond the ESP32-WROOM-32D/U as I presume there will be more active and passive components on the board, including power supply (BTW, carefully select the electrolytic capacitors, which characteristics are affected by both high and low tempera...

Re: ESP32 PCB Antenna Design

Hi Prasad, you can download the modules' reference designs from www.espressif.com/en/support/download/documents , ESP32-WROOM-32D and ESP32-WROVER-B have the latest antenna designs. You may also directly use modules, unless you have reasons for designing your own layout.
