**The breakout board accessory is not compatible or needed on Elite machines using the Masso controller. It is only compatible for non-elite machines using the buildbotics controller.** Info on the breakout board accessory: The breakout board is NOT included with the machine. If we included the breakout board with every machine, the cost would go up for everyone (granted it would be smaller, but more is more). The way the controller is now, we figure most customers would never need or use the breakout board (but they would get charged for it). By making the breakout board a optional item, the only customers that would pay for it are those that actually would use it. Again, if you purchase our probe and/or laser, they will plug directly into the controller without the need for the breakout board (we tried to make it as plug and play as possible, eliminating the need for soldering). If you have your own and want to save money by not purchasing the breakout board, you can purchase the connector for the wire ends and attach them yourself (here’s a link to them : (the connector [https://www.digikey.ca/short/z41jmj](https://www.digikey.ca/short/z41jmj) ) (the pin [https://www.digikey.ca/short/z41j9w](https://www.digikey.ca/short/z41j9w)) ). They are $.16 cents and $.27 cents. We’ve tried to give the customers many options. One thing we did NOT do is make anything proprietary, by locking customers out of using their own accessories. You can purchase the [breakout board HERE](https://www.onefinitycnc.com/product-page/breakout-board-adapter). For those that use a VFD/Spindle you will need to purchase the breakout board. There’s no connector on the controller for it. These are much more complicated and there was no way around it. ![f704eb_b7b13a7ecbf94604a8a6032359fda99b_mv2](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/5/1/5181c6cc579a984532ae737221301b9b3af06c6e.jpeg) **Wiring Schematic:** ![Screenshot 2022-02-02 135701](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/2X/1/1619c0ce5f2aa28e02c94caa7c99b53096ade52e.jpeg) ---

I’m hoping to be able to use it to tie into a tool head on/off. This worked on my old CNC and was nice to have the router turn on and off automatically. Then you hook it to something [like this.](https://smile.amazon.com/Iot-Relay-Enclosed-High-Power-Raspberry/dp/B00WV7GMA2/ref=sr_1_1?crid=100IXMMSM7QO8&dchild=1&keywords=iot+power+relay&qid=1598903904&sprefix=iot+%2Caps%2C144&sr=8-1) ---

Looking at the breakout board FAQ ([What Does The Breakout Board Do?](https://forum.onefinitycnc.com/t/what-does-the-breakout-board-do/1766)) and hoping to setup a second relay to turn on\off a second monitor\RPi for showing the controller page with model\carve preview. My understanding is I can connect the vcc to the 3.3v (pin 6) and gnd (pin 7) but then what do I use for signal? Do I use Load-1 (Pin 1) or Load-2 (Pin 2)? If so what do I configure in the controller under IO | Outputs for that? Am I on the right track or is there a better option? A time delay would also be fantastic so that the controller would boot first but, baby steps… well maybe ogre steps… not real graceful in these new electronic spaces. ---

Ok, so tell me … I have a Spindle/VFD sitting on the bench awaiting its Onefinity. Do I still need Onefinities breakout board or is there a card in the controller?? ---

Does anyone know where I can find more detailed technical documentation on the breakout board? Specifically, I’d like to get more details on each pin. Are they all output pins, or are these some input pins (other than maybe EStop)? For example, if I wanted to connect my own EStop button, do I just pull that pin down to GND? Documentation such as that is what I’m looking for. ---

I’m glad the pricey breakout board is not included. I just needed 1 signal and GND to control the relay to turn the router off and on, and a DB-25 connector plus hood was less than $2 from Digikey. Anyone with crimping or soldering capability doesn’t need the breakout board. ---

I have a Masso G3 controller not the Touch, but it is basically the same hardware/software. The controller will control the spindle RPM through your Gcode, but it also has a an override slider on the screen that can adjust RPM while machining. I believe the BOB is meant for the original controller, when the functionality it offers is wanted by the user. ---

Hey Greg, the breakout board adapter is nothing than a [25-pin D-Sub](https://en.wikipedia.org/wiki/D-subminiature) to [screw terminal](https://en.wikipedia.org/wiki/Screw_terminal_block) adapter. It can be used on any device that has a 25-pin D-Sub port. Such adapters are a standard electronics part and are available everywhere. On the 👉 [Onefinity Original Series Controller](https://www.onefinitycnc.com/_files/ugd/1cee9f_bed246d0462e443ab8f782f2384d4ddb.pdf), it allows you to attach devices like optocouplers, relays or sensors in order to be able to e.g. - automatically control router on/off with [M3/M5](https://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m3-m4-m5) - automatically control dust collector on/off with M3/M5 - automatically control workpiece coolant pump on/off with [M7/M8](https://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m7-m8-m9) - to have a serial communication with a VFD/spinde that is ModBus-compatible - to have analog speed control of a PWM spindle - to [retrofit inductive proximity sensors](https://forum.onefinitycnc.com/t/controller-software-tool-change-location-0-0-g54-g55-g56/10052/14) as limit switches to the machine to no longer have to use [stall homing](https://forum.onefinitycnc.com/t/how-common-are-missed-steps/18352/8) Here you find the [pin assignment of the 25-pin I/O port on the 👉 Onefinity/Buildbotics controller](https://buildbotics.com/manual-v1-0/#25pinioport). ---
