Product description: Feather RP2040 24-pin E-Paper - board with RP2040 microcontroller and display connector - Adafruit 5727
Adafruit Feather RP2040 with a 24-pin connector for connecting E-Paper displays is a board based on the RP2040 microcontroller, with a dual-core ARM Cortex M0+ with a clock speed of up to 133 MHz, equipped with 264 kB of RAM and 8 MB of Flash memory operating via the QSPI interface. The microcontroller is equipped with such interfaces as: 2 x I2C , 2 x SPI , 2 x UART, 16 PWM channels and 4 x ADC . The 24-pin connector on the board allows you to connect any E-Paper display that uses this interface. There is also a STEMMA QT connector at the user's disposal for easy connection of modules using the I2C interface without the need for soldering.
The RP2040-based platform supports many programming languages, such as MicroPython , CircuitPython and C/C++ . The program can be implemented using the USB interface (USB type C connector), using the built-in UF2 bootloader, or through an external programmer. In addition, the board has a red LED and a Neopixel RGB LED.
Feather RP2040 24-pin E-Paper - board with RP2040 microcontroller and display connector - Adafruit.
The board has a JST connector, which can be used to connect the battery to it.
Connecting an external battery
The JST connector is used to connect a lithium-ion (Li-Ion) or lithium polymer (LiPol) battery to power the board. After connecting the power supply via the USB connector, the built-in charging system allows you to charge the battery with a maximum current of 200 mA. The charging status is indicated by a dedicated LED. The system detects the connection of the power supply, thanks to which it is possible to use the battery as a UPS.
Do not connect batteries other than those indicated by the manufacturer - Li-Ion, Li-Pol - with a maximum voltage of 4.2 V to the JST port. This may damage the charging system.
