The LMS/SPIKE OpenMV converter connects your SPIKE Prime to your OpenMV camera board, or to the esp-i2c-wifi board.In the converter breadboard package you will find: 2×8 pin headers, 0.1 inch pitch a grove port 2x 6 pin ports 2x 6 pin plugs 1x Wedo 2.0 or LEGO Power Functions 2.0 wire.The 6 pin plug shrinks perfectly on a repurposed Wedo or Power Functions 2.0 wire, no tools needed! I ordered the wires online from China. One is included in the kit, you can order a second one yourself. Ultimate connectivity for all your LEGO bricksIn the wiki and projects repository, we are continuously adding manuals and example projects with this board. We haven’t made examples for everything yet, but with the design of the board, we had these connections in mind: SPIKE/RI to SPIKE/RI uart connection SPIKE/RI to EV3 uart connection SPIKE/RI to OpenMV uart connection EV3 to OpenMV uart connection SPIKE/RI to ESP WiFi board with i2c OpenMV i2c on pins 7 & 8 to grove or 0.1″ headersThe EV3/SPIKE OpenMV convertor board has the following applications: Connect a WiFi ESP board to your SPIKE Prime or Robot Inventor hub Connect an OpenMV AI camera to your SPIKE Prime, Robot Inventor or EV3 hub. Create wired communication between all your Lego Power Functions 2.0 and NXT/Ev3 devicesLMS-uart-convertor 1.0 pinoutIn the pinout, you can see that the board makes all uart rx/tx connections. The I2C connections require a board below this board. That could be an OpenMV camera or an ESP wifi board. LEGO smart hubs have internal resistors that mess with pull-up resistors in the most common i2c devices, so they are hard to connect directly. You can also use jumper wires and headers at the bottom of the board to connect LEGO line 6 to SDA and LEGO line 5 to SCL.Because motor lines (lines 1 and 2) can generate up to 9V, they are not connected by default. The board has soldering jumpers to connect them. The motor lines can be handy to power LED arrays that take a lot of current. Be careful not to fry any 4v7 or 3v3 logic when you do.Here’s one of my experiments where I use the board:Warning: there’s no warranty for this product!Soldering guide:DISCLAIMERWe have been very careful designing this breakout board, to make it near impossible to create connections that damage your LEGO.
