Mx230 Pyro Board
The Mx230 Pyro Board is an optional accessory that plugs onto the backside of an Mx210 Kate-3 transmitter and adds deployment and staging capability. An apogee event can be fired with GPS precision even at altitudes that reach into space! In fact, all deployment and staging events are triggered by GPS data. However, the accelerometer, gyro, barometric pressure sensor, timer and even manual command can also be used as back-up redundant triggers. All events can be configured with the Mx220 Receiver. No computer is needed. The receiver has an interactive electronic Go/No-Go checklist that guides the user during setup prior to launch.
Mx230 Option-10 Long Skinny Mounting Option
Mx230 Option-10 is a "long skinny" configuration that allows the Mx210 transmitter and Mx230 pyro board to be mounted back-to-back and fit inside a 2" ID tube (i.e. 54mm coupler tube). It is intended for smaller diameter nosecones. It includes the Li-ion system electronics battery and the pyro battery. Everything is in one package. There is also an aft bulkhead that includes an anchor bracket for connection to a recovery harness.
Mx230 Option-20 Outrigger Mounting Option
Mx230 Option-20 is an outrigger mounting option that allows the Mx210 transmitter and Mx230 pyro board to be mounted back-to-back. It provides six holes for mounting the whole assembly onto an avionics bay sled. The user will also need to mount the Li-ion electronics battery and the pyro battery to the sled. (Batteries not shown here.)
Optional Battery Board
The Mx230 Option-20 outrigger mounting scheme was originally designed to allow the user to mount the system battery and the pyro battery somewhere on the user's custom sled. However, a new optional battery mount board is now available that provides a very convenient mounting platform for the batteries. It has the same dimensions as the Option-20 outrigger board shown above and the exact same mounting hole pattern. It mounts neatly and compactly over the top of the transmitter while still allowing access to the power switch, LED's and USB connector. It provides secure mounts for both batteries.
This is a short HD video (47 seconds) that shows a 360 degree view of the battery board mounted to the Mx210 Kate-3 transmitter and pyro board. Be sure to expand it out to full screen to get a good look at the entire package. (There is no sound.)
Mx230 Option-25 Configuration
The Mx230 Option-25 configuration shown below is the same as the Option-20 but with the Option-25 battery board installed. The Mx210 transmitter and Mx230 pyro board are mounted back-to-back. The Li-ion system battery and the pyro battery are mounted over the top of the transmitter but still allow access to the power-switch, LED's and USB connector. This configuration provides three mounting points along each side edge. There are 4-40 screws and threaded standoffs at those mounting points that bolt the battery board to the outrigger board. Those existing screws can be used (or replaced with longer ones if necessary) to mount the whole assembly onto an avionics bay sled.
Mx230 Option-30 Extended Outrigger Configuration
Mx230 Option-30 is an extended outrigger mounting option that allows the Mx210 transmitter and Mx230 pyro board to be mounted back-to-back. It provides ten holes for mounting the whole assembly onto an avionics bay sled. It includes mounts for the Li-ion system battery and the pyro battery.
Wondering what version of transmitter to buy?
Here are a few tradeoffs to consider.
Here are a few tradeoffs to consider.
Option-10 is usually mounted by placing it inside an 54mm coupler tube. It can be used on 54mm and larger rockets. However, being so skinny, it ends up being pretty long in order to fit everything together. Option-20 is easier to mount on a sled or other structure and fits in airframes and nosecones 3” in diameter or larger. With option-20 the batteries are completely separate. You will need to figure out how to mount them on your sled or whatever structure you create. However, this generally allows option-20 to require less overall length since you are taking advantage of a larger diameter. Option-25 is the same as Option-20 but adds an extra battery board that is bolted onto the Option-20 unit to hold the batteries. This eliminates the need to create your own battery holders on your sled. Option-25 also fits in 3” and larger diameters. Option-25 can be mounted to a sled using the same screws that bolt the battery board to the unit. With Option-25 your can also remove the battery board if you want, and you are left with the Option-20 configuration. Option-30 is for situations where length and width are of no concern. It is very long but has everything packaged together and has lots of mounting screw holes available along its entire length.

Mx151 Antenna Mount
The Mx151 antenna board attaches to the front end of the transmitter and provides connections for the downlink antenna and the GPS antenna. In some situations, it can be advantages to mount the antenna board separate from the rest of the system and connect it with extension cables. However, this is not recommended without first consulting with Multitronix to discuss your installation.
