MR-MCXN-T1 Add-on boards

[!NOTE] Different Add-on boards have been designed for the modular multi-purpose MR-MCXN-T1 Hub.

The following add-on boards have been designed:

• Optical Flow
• IO
• GNSS (with F9P module) ¹

All add-on boards are designed with KiCAD.

MR-MCXN-T1 Optical Flow

[!NOTE] The Optical Flow add-on board can be used in for instance UAVs and UGVs for localization and navigation using the following on-board sensors:

• Time of Flight (AFBR-S50LX85D)
• Optical Flow (PAA3905E1) + required light source
• IMU 2x (ICM-45686 & ICM42688)

MR-MCXN-T1 IO

[!Note] MR-MCXN-T1 IO board brings out almost all GPIO to JST connectors. These are as follows:

IO type	Connector type
UART 2x	JST GH 6-pin
SPI 2x	JST GH 7-pin
I2C 2x	JST GH 4-pin
GPS	JST GH 10-pin
Quadrature Decoder	JST GH 6-pin
4in1 ESC 2x	JST GH 8-pin
External battery input for RTC	JST GH 2-pin

If applicable the connector pinouts follow the DS-009 Connector Standard.
