Pequeno e potente!

Este produto usa o chip SX1278 para as comunicações LoRa e um ESP32 como Processador Principal. De base o processador ESP32 disponibiliza WiFi e Bluetooth.

Dispõe ainda de um muito útil display onde poderá apresentar informação relativa a sensores (não incluídos) que possa adicionar ao seu projecto, bem como dados recebidos através da rede ou até fazer debug do seu código.

Notas: Fornecido com headers não soldados e cabo para a bateria. Não incluí bateria. Poderá encontra uma bateria aqui (Não se esqueça de validar a polaridade antes de ligar a bateria!)

Descrição

Se tiver alguma dúvida neste produto não hesite em contactar-nos.

*Atenção: as imagens são meramente ilustrativas.

The 433MHz antenna must be used in conjunction with the IPEX interface (if the antenna is not connected, it may damage the LoRa chip)

Lithium battery charging and discharging circuit, when the battery is full, the blue LED will stop working. When using, pay attention to the positive and negative of the battery, otherwise it will be damaged.

Note:This product does not include the battery.
Using the IO port touch screen touch signal input, you need to add the 100nF pull-down capacitor at this pin!

Package included:

1 x ESP32 OLED
1 x Line
2 x pin
1 x 433m Spring Antenna

Example:

This product is a SX1278 chip based on ESP32 WIFI increased, OLED, namely LoRa remote modem, 433MHz frequency, high sensitivity is about -148dBm, +20dBm output power, high reliability, long transmission distance.
The onboard 16 Mt bytes (128 Mt bit), Wi-Fi antenna, 0.96 inch blue OLED display, lithium battery charging circuit, CP2102 interface and USB serial chip, the perfect support for development environment, can be used for program verification and product development is very simple and fast.
