Grove - IMU 9 DoF
Version från den 4 februari 2021 kl. 07.27 av Christian (diskussion | bidrag)
IMU 9 DoF är en högpresterande 9-axels rörelsespårningsmodul. Det är en integrerad 9-axlig rörelsespårningsenhet som är utformad för att tillgodose kraven på låg effekt, låg kostnad och hög prestanda i hemelektronikutrustning, inklusive smartphones, tabletter och bärbara sensorer.
Kompatibilitet
- Arduino
Port
- I2C
