This add-on provides access to 3V, 5V, GND, I2C, and 6 GPIO on your Apollo Automation MSR-2 sensor via the mezzanine port. Connected sensors can be powered by the 5V GPIO pin. An example showing the GPIO header controlling an LED strip can be found here. Comes with a 3D-printed panel to fit your existing MSR-2 case, giving access to the GPIO adapter. The adapter itself can be used with any Apollo Automation product with the mezzanine connector, however the included 3D-printed plate will only fit the MSR-2. MSR-2 not included. Features * Breakout access to 3V, 5V, GND, I2C, and 6 GPIO pins * Connects to the mezzanine port of the Apollo Automation MSR-2 * Also works with other Apollo Automation products with mezzanine ports * Supports powering connected sensors via 5V GPIO pin * Suitable for GPIO-controlled peripherals (e.g. LED strips) * 3D-printed adapter plate included Resources * Adding GPIO Header to MSR-2 * How to Use the Apollo GPIO Header to Control an LED Strip Pinout Package Contents * 1x GPIO Add-on for Apollo Automation MSR-2 * 1x 3D printed adapter panel for MSR-2 MSR-2 not included. https://elecena.pl/product/28454477/gpio-add-on-for-apollo-automation-msr-2 2025-04-17 https://elecena.pl/product/28454477/gpio-add-on-for-apollo-automation-msr-2 2025-07-25 https://elecena.pl/product/28454477/gpio-add-on-for-apollo-automation-msr-2 2025-07-31 https://elecena.pl/product/28454477/gpio-add-on-for-apollo-automation-msr-2 2025-11-28 https://elecena.pl/product/28454477/gpio-add-on-for-apollo-automation-msr-2 2025-11-29
