| #################### | ||||||
|
|
||||||
| Overview | ||||||
| ******** | ||||||
|
|
||||||
| The camera module bundle (B-CAMS-OMV) provides extension connectors | ||||||
| for the MB1379 STMicroelectronics camera module daughterboard or | ||||||
| third-party modules like OpenMV and Waveshare modules. It can be used | ||||||
| with the STM32 boards featuring a 1 x 30 pin ZIF connector for the | ||||||
| connection of multiple cameras to implement computer vision on STM32 | ||||||
| microcontrollers easily. | ||||||
|
|
||||||
| The camera module bundle is compatible with all STM32 Discovery kits and | ||||||
| Evaluation boards featuring a ZIF connector, such as the STM32H747I-DISCO, | ||||||
| STM32H7B3I-DK, and 32L4R9IDISCOVERY Discovery kits. | ||||||
