- IBK-BLYST-NANO: Breakout board - IDK-BLYST-NANO: DevKit board with builtin IDAP-M CMSIS-DAP Debug JTAG, RGB led - BLUEIO-TAG-EVIM: Sensor tag board (environmental sensor (T, H, P, Air quality) + 9 axis motion sensor) Also, the LED module has been updated to support individual base level configuration of each LED. If set, this will be used instead of the common configuration, MICROPY_HW_LED_PULLUP. The new configuration, MICROPY_HW_LEDX_LEVEL, where X is the LED number can be used to set the base level of the specific LED.
