Product detailed description

Development board with ESP32-WROOM microcontroller specifically designed for ultra-low power battery powered IoT applications. Thanks to its choice of components and circuit design, it is one of the boards with extremely low power consumption in sleep mode. Also the type of microcontroller used - SoC ESP32 predestines this board for high-performance IoT applications. The board also contains an integrated charger for one Li-ION cell, which is then powered by the board. With this board, you no longer have to choose between power and power consumption, so you can focus on your own application development with almost no limitations.

The board does not include an integrated programmer, which also saves power and allows the board to maintain a very small footprint. The spacing of the I/O pins was deliberately chosen so that the entire board can be inserted into a non-soldering contact field during the development phase, which can greatly simplify the initial design of the application under development.

For these boards, and not only for them, we have also created a suitable programmer, which will make programming this board a breeze. When using our programmer, it is no longer necessary to press any buttons before programming, as with some similar boards.

You will need a 2.4GHz antenna, for example

Specifications:

ESP32 module ESP32-WROOM-32U 16MB
Input voltage 3.7-8V
Power consumption in deep-sleep mode 16.5μA (standalone board without connected peripherals)
Digital I/O Pins 32
Analog Inputs 16
Dimensions
Length 62mm
Width 25.5mm
Height 10mm
Weight 10.3g


Delivery components:

  • 1pc LaskaKit ESP32-LPKit IPEX antenna
  • 1pc 6pin hollow rail for programmer connection

Remark:

  • This board is a 3.3V device. If you need to connect 5V digital sensors or devices, you will need a voltage level converter such as our 4-channel or 8-channel converter modules.
  • Programmer, pin and hollow rails are not included
  • This product is not a standalone functional unit and may require professional installation.
  • Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.

Poprvé jsem nahrál ArduinoOTA do ESP a pak už jen modifikuji pomocí OTA. Vše funkční spotřebu jsem zatím neměřil. Spokojenost.

Zdravím, mohu získat stav baterie přes pin "BAT_ADC", nebo musím připojit rezistory? popř. k čemu tento pin slouží?

Dobrý den, odporový dělič již na desce k tomuto účelu je. Jen je potřeba propájet propojku ADC(BAT_ADC). Potom by mělo být možné přímo číst napětí baterie na analogovém pinu IO34.

Deklarované vstupní napětí 3,7-8V je přes JST/battery konektor? Micro usb slouží POUZE? (viz github) k nabíjení baterie a musí mít standardních 5V? Není možné přímé připojení solárního panelu na USB či VIN pin? Děkuji
