Product detailed description

The board integrates a wireless WiFi module with ESP-32 chip and a USB interface from which the module can be powered and programmed. Communication is provided by the CP2102 controller. The ESP-32 module itself is equipped with a highly integrated and powerful 32-bit microprocessor with many GPIO pins, that can perform the action according to the programmed code even without using the Arduino control.

The board is compatible with Arduino IDE and NodeMCU.

The board has a USB Micro connector and a USB to serial (UART) converter, making it easy to connect this board to your computer using a USB Micro cable.

LiPol charging is handled by TP4054, max charging 500mA, JST-PH-2 connector

Při připojení PCF8583 (I2C) a teploměru DS18B20, kód při zapnutí WIFI zvykne zahlásit 'Brownout detector was triggered' - což podle mě naznačuje že deska by si zasloužila více kondenzátoru.

Paráda, funguje jak má. Navíc byl pořádně zabalený při přepravě, takže žádné ohnuté nožky a tak. Trochu jsem ze začátku válčil se správným výběrem PINů pro SPI, ale zdařilo se.

Konektor na baterii není JST-XH 2.54, ale podle všeho je to JST-PH 2.
