-Same as Nano33 Ble: same Pinout pin layout, same RGB three-color LED, factory preset Nano 33 Ble Bootloader Differences from Nano 33 Ble: Added lithium battery charging management, the back pad can adjust the charging current (default 100ma, short circuit 500ma) Reserved sensor pin package (no device attached): MP34DT06JTR (microphone) Sensor pin packages are not reserved (but related pin pads are lead out): LPS22 (pressure sensor), LSM9DS1 (accelerometer gyroscope), HTS221 (humidity sensor) sensor), APDS-9960 (gesture sensor)+===   Same as Nano33 Ble:   ===
