The Shield is based on the L298 (datasheet)

The NeoPixel RGBW Shield – Warm White features 40 individually addressable RGBW LEDs in a 5×8 matrix

The SHT20 I2C temperature & humidity sensor adopts Sensirion techniques

"Standard Mode" does not require this calibration routine

This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)

Gravity: SGP40 Air Quality Sensor Brand_M5Stack The Shield is based onThe SGP40 Air Quality sensor adopts the new SGP40 digital VOC sensor chip launched by the well known Sensirion. Based on the Sensirions CMOSens technology, the SGP40 offers a complete sensor system on a single chip, a temperature controlled micro hotplate and a humidity compensated indoor air quality signal. In combination with Sensirions powerful VOC algorithm, the sensor signal can be directly used to evaluate indoor air quality. It features low
