REV Expansion Hub Component Updates
Published by Greg Needel on Dec 13th 2021
From this point forward, REV Expansion Hubs will no longer include an IMU (Bosch BNO055 Inertial Measurement Unit).
When the REV FTC Control System was first implemented, it featured two Expansion Hubs and a phone. We originally elected to include IMUs in all Expansion Hubs, even though most teams only utilized one. As the FTC Control System evolved, the REV Control Hub was introduced, which also includes an IMU. After experiencing shortages of many of the electronic components that go into our products, we faced the difficult decision of waiting for devices, re-designing for another part mid-season, or removing the IMU from the Expansion Hub. We decided that removal was the best option. All REV Expansion Hubs purchased on or after December 1, 2021 will no longer include an IMU. This change is permanent and all future expansion hubs will no longer include this component. Refurbished Expansion Hubs that are received after repair services are not guaranteed to have an IMU.
