SuperMini nRF52840 is a nice!nano alternative development board. All the pins are compatible with nice!nano, except P1.01/02/07 GPIOs broken out onto their own pins (see the footprint). Pins are the same as Pro Micro, which means it can be used with almost any Pro Micro compatible keyboard. SuperMini NRF52840 development board supports ZMK Firmware. Features Bluetooth 5.0 Microcontroller nRF52840 ARM Cortex-M4F processor Clocked at 64MHz Flash Memory 1MB RAM 256KB Quiescent Current (power consumption at sleep mode 1mA) Battery charging chip: supports lithium battery charging and discharging dual-current Li-Po charging with a jumper that you solder with max of 300mA software-controllable MOSFET on the VCC pin to cut standby current consumption of LEDs and other peripherals (in theory, i still need to test this) nice!nano bootloader pre-flashed Dimensions33mm (H) x 17.78mm (W)Includes1 x SuperMini nRF52840 Controller
