1.5A current limited
With EMI Filtering and TVS protection - A μSD Card socket capable of 25MB/s reads/writes which allows your OpenMV Cam to take pictures and easily pull machine vision assets off of the μSD card.
With EMI Filtering and TVS protection - A SPI bus that can run up to 60Mb/s allowing you to easily stream image data off the system to either the LCD Shield or another microcontroller
- An I2C Bus (up to 1Mb/s), CAN Bus (up to 1Mb/s), and an Asynchronous Serial Bus (TX/RX, up to 20Mb/s) for interfacing with other microcontrollers and sensors

- Three I/O pins for servo control
- One I/O pin for frame sync/triggering (or servo control)
- An onboard RTC which keeps running when the system is in low-power mode (the system draws less than 30uA in low-power mode)
One I/O pin for low power wake up
There is also a pin for device power button ON/OFF support - Interrupts on all I/O pins (there are 14 I/O pins on the board)
With EMI Filtering and TVS protection - A user controllable/dimmable RGB LED
- Another RGB LED for Charging, USB Power, VIN Power indication
- 32 MB of external 16-bit SDRAM clocked at 160 MHz for 320 MB/s of bandwidth
- 16 MB of program/storage quad SPI flash clocked at 133 MHz in 4-bit SDR mode for 66 MB/s of bandwidth (read speed)
- A 12-bit X/Y/Z accelerometer (2/4/8g) centered underneath the camera module
- Onboard WiFi (a/b/g/n - 11/54/65 Mb/s) and Bluetooth (v5.1 - BR/EDR/BLE) module with a chip antenna
Option to use a U.FL antenna instead - Onboard 10/100 Mb/s Ethernet
Ethernet Jack with PoE support via an external shield - Strong Cryptographic Authentication Secure Element support via the SE050C1HQ1
A removable camera module system allowing the OpenMV Cam RT1062 to interface with different sensors:
- The OpenMV Cam RT1062 comes with an OV5640 image sensor that is capable of taking 2592x1944 (5MP) images. Most simple algorithms will run about 40 FPS on QVGA (320x240) resolutions and below. If you want to use more specialized lenses with your image sensor you can easily buy and attach them yourself

- OpenMV Cam RT1060 is a compact, low-power microcontroller board with camera, facilitates the seamless implementation of real-world applications using machine vision. Programming of the OpenMV Cam is accomplished through high-level Python scripts, courtesy of the MicroPython Operating System, as opposed to C/C++. This approach simplifies the handling of complex outputs from machine vision algorithms and the manipulation of high-level data structures. Despite this, total control over the OpenMV Cam and its I/O pins remains within reach through Python. Triggering of picture-taking and video recording based on external events is straightforward, as is the execution of machine vision algorithms to manage I/O pin control.
