LaskaKit microESP
Code: LA100050Product detailed description
As you can see in the picture above, there's a lot on the board. The board is powered by a connected battery, which can be charged via an integrated charge controller from the solar panel. The nominal voltage of the solar panel is recommended to be 5V or 6V.
We also added our μŠup connector to the board, to which you can connect various I2C sensors very conveniently and safely. The connector ensures a secure connection thanks to a built-in lock in the connector. Sensors that fit this development board are for example SHT40 (temperature and humidity sensor) or SCD41 (CO2, temperature, humidity sensor. But even though we put an I2C sensor connector, we used the space to add more GPIOs on the sides of the module. We have also brought out the RX and TX UART buses, so if you have a sensor that communicates via UART, there is no problem to use it with microESP.
On the upper side there are two soldering bridges. One is for battery voltage measurement (output after the battery voltage divider is connected to IO0). Resistor R1 is 1M, R2 is 1.3M, maximum input voltage (at 3.3V ADC reference) is 5.8V. The last soldering bridge is the connection of pull-up resistors on the I2C bus (SDA - IO8, SCL - IO10).
To program this miniature and very economical board, you need to connect a USB-C cable to your computer and switch the ESP32-C3 to bootloader mode with the following trick. Connect USB-C to microESP and computer. Press and hold the FLASH button. Press and release the RESET button. Release the FLASH button.
