BETAFPV posts separate Matrix 1S firmware images for two gyro variants
BETAFPV updated its Matrix 1S Brushless Flight Controller support page on 22 September with Betaflight 2026.6.1 firmware for BMI270 and ICM42688 gyro versions. The company explicitly warns that each image is compatible only with the matching gyro model.

Two boards sold under the same product family can require different firmware. Flashing by product name alone is not enough when component variants change the target image.
Identify the gyro before flashing and use the matching file. BETAFPV also recommends Betaflight Configurator 10.10.0 and advises against operating the aircraft below 3.4 V.
