A good option to discover the WROVER. 2 Remarks : - But careful : only one way at a time to power the board (USB/5V/3.3V). - The boards with the I option have then an IPEX connector for an external antenna, but also a PCB antenna ; however, this antenna isn't connected ! On the schematic (cf. WROVER datasheet), there are 2 resistances R14 and R15 (0 Ohms in fact) and only one is present, toward the IPEX connector (I option) OR toward the PCB antenna (no I option). So, with the I option, it's possible to use the PCB antenna, but with a little solder work...

Placa chegou dentro do prazo previsto, porém a embalagem era totalmente inadequada e um dos pinos veio torto. Fora isso tudo Ok com a placa... está funcionando!
