The X10+ Channel Expander is a small device that acts as a power expander, channel expander, voltage monitor, and failsafe system for different types of receivers that output a serial data stream. So, FrSky X Series, XPS Nano, Nano II, & RFU, JR DMSS X-Bus (Mode A & Mode B), Futaba SBUS/SBUS2, Graupner HoTT SUMD, JETI UDI, and Spektrum satellite receivers are all supported. ALL types of servos are supported.
The X10+ is called "+" because it can output up to 10 channels, and with the auxiliary port set to an output, an 11th channel is available. The auxiliary port can also be an input for a 2nd receiver for true RF redundancy!
The X10+ has a heavy duty (up to 10awg wire) power inputs, allowing you to power the servo bus properly! As part of our testing, we made the servo bus into a 'fuse' between power connections and pulled 80A@12v with no overheating of the servo bus. So, it is more than sufficient for powering servos! You can power the X10+ using the normal servo ports, like a traditional receiver too. Keep in the mind that the power going into the X10+ is the power also coming out of it. So, if you plan to power your setup using a 2S Lipo, MAKE SURE that your receiver and servos can handle a 2S Lipo setup! There is NO voltage regulator for the receiver (with exception of the special Spektrum jumper mod to provide 3.3v to the satellite receiver, more on that below).
The X10+ has our popular TattleTale built-in, the lowest voltage captured is shown as a color. If your LED turns yellow it means the input voltage dropped below 4.5v for at least one frame period in time (11ms-22ms, depending on the radio system connected). This device does NOT lie... so don't ignore a color change - you most definitely have a problem when the LED is not solid green!
The X10+ has a serial interface for our new Serial Link. The Serial Link is a USB device that plugs into any USB port on a Windows PC. Windows 95 through 8.1 is supported. Our normal XDP software package has been upgraded to be fully compatible with the Serial Link. So, using the XDP.exe program, you can upgrade firmware, and change any settings - such as channel mapping, failsafe mapping, failsafe time, reverse servos, change offsets (matching), etc. Most of these functions can also be programmed by using just the push button and LED. The Serial Link is required to upgrade the X10+ firmware
The X10+ servo outputs are nearly simultaneous, with just 71 microseconds maximum time between servo outputs! This means that customers using non-XPS receivers will for the first time ever have servo outputs that occur at virtually the exact same time. This make a huge difference in swash plate manipulations, split elevators, etc.
The X10+ has a failsafe override (on by default). This means that it will ignore the failsafe of the receiver and use it's own failsafe settings. If you don't have failsafe override enabled, then the receiver will provide the failsafe control. With the failsafe override enabled you can independently set the failsafe for every single channel. There are three different failsafe types you can choose from: hold last position, user defined position, or signal off (handy for autopilots that use a loss of servo pulse to trigger a return to home function). Every channel can have a different preset position, and it is done with our live active failsafe. This is accomplished by pressing the button on the X10+ for 2 seconds, at which point you now have 7 seconds to move the controls to where you want them to be during a failsafe condition. Once the failsafe positions are 'locked' into memory, any channel that has had its failsafe type defined as 'user defined' will now go to that position when a failsafe occurs!
Spektrum satellite receivers can be powered directly by the X10+ when using a special solder bridge jumper. This provides 3.3v to the receiver (instead of the normal servo voltage). This means you don't need the adapter cable commonly used with Spektrum satellite receivers to convert 5v to 3.3v. A 2nd satellite receiver in the AUX port requires a power adapter.
These boards are conformal coated to make them water resistant.
Keep in mind that you can use as many X10+ boards as you like in the SAME system! You just use Y-cable(s) to connect the serial data connection from the receiver to each X10+ setup.
The X10+ operates down to 1.8 volts! This is well below the operational voltage of ANY servo and ANY other brand of receiver. So, the X10+ stays fully operational in the lowest voltage conditions.
NOTE: Digital servos should be used with the X10+ as the framerate will be the same as the Sbus source. While analog servos may work for a while, they will probably fail in a short time.

The X10+ is just what I needed to provide increased current capacity to an new 11 channel glider with 8 digital servos plus retract and spoilers. Although the average current draw or the airplane is within the capability of the FrySky X8R, the peak draw is likely to be much higher. I've paired the X10+ with a X4R-SB rcvr. A capable combo at a fraction of the cost of a competitor's 'power safe' receiver, and greater flexibility. Maiden flights were a delight.
