Accessories Bags
Bag #1
Bag #1 contains the [30P-PicoClasp Header + MRC0272 + MRC0277] combined with the [Micro USB Cable], which offers a quick way to attach your autopilot to your PC. The MRC0272 is the female USB cable socket and the MRC0277 is the 6-position, red and black cable with a JST-GH header to attach your GPS. We recommend always keeping this harness on the ground and only using it for quick testing, firmware updates, and/or diagnosis.
This bag also contains the enclosure (optional) and SD Card. Note that depending on the SD Card packaging dimensions, it might sometimes be located outside the bag.
1 x Micro USB Cable
1 x 30P-PicoClasp Header + MRC0272 + MRC0271: 6P-PicoClasp Crimps to 6P-JST-GH Header (Red&Blk)
1 x Enclosure
1 x 8GB SD Card (sometimes outside the bag)
Bag #2
This bag contains 2x red and black MRC0271 cables that will allow you to quickly attach your GPS and/or Telemetry modules that are JST-GH compatible. Please refer to Bag #3 for more PicoClasp to JST-GH for more options.
The remaining white cables [MRC0274, 5, 6 & 7] have PicoClasp crimps on one side and a “bare” cable on the other. Those are optional cables that allow advanced users to solder them to other hardware, or for pure development purposes.
2 x MRC0271: 6P-PicoClasp Crimps to 6P-JST-GH Header
1 x MRC0272: 4Pos-PicoClasp to Female Micro USB Socket
1 x MRC0274: 6P-PicoClasp Crimps to Bare-Tin
1 x MRC0275: 5P-PicoClasp Crimps to Bare-Tin
1 x MRC0276: 3P-PicoClasp Crimps to Bare-Tin
1 x MRC0277: 2P-PicoClasp Crimps to Bare-Tin
1 x MRC0278: 6P-PicoClasp Crimps to Bare-Tin (Red&Blk)
4 x 30P-PicoClasp Headers
Bag #3
This bag contains everything that is needed to assemble your own custom harnesses and interface between the two onboard mRo Control Zero 30-pin PicoClaps connectors to the standard JST-GH header with 4 and 6 positions. The JST-GH is commonly used for CAN, GPS, Telemetry, and Power modules.
We have included enough “pre-crimped” PicoClaps to JST-GH cables with different lengths and JST-GH Housings to allow you to build any possible configuration. You won’t use most of the cables included, they are just there to give you maximum flexibility. You can obtain more housings at our store to take advantage of the remaining cables, or you can just save them as spare parts.

1 x MRC0280-300mm: 12P-PicoClasp Crimps to JST-GH Crimps
Bag #4
This bag contains everything needed to create your own harnesses to attach servos to the mRo Control Zero autopilot.
Use the M10067 board to interface with standard 2.54mm servos or the M10068 board for the standard mini servos connector. With some creativity, both boards can be used simultaneously to control a mix of standard and mini servos.
Note that not all of the MRC0281-xxx cables are expected to be used; only grab the length that fits your needs.
2 x 10P-PicoClasp Housing
2 x MRC0281-50mm: 12P-PicoClasp Crimp to PicoClasp Crimp
2 x MRC0281-100mm: 12P-PicoClasp Crimp to PicoClasp Crimp
2 x MRC0281-200mm: 12P-PicoClasp Crimp to PicoClasp Crimp
1 x MRC0281-300mm: 12P-PicoClasp Crimp to PicoClasp Crimp
1 x M10067 (Board): 10P-PicoClasp Housing to 8x Servo Header
1 x M10068 (Board): 10P-PicoClasp Housing to 8x Mini Servo Header
Bag #5
This bag contains standard 2.54mm connectors to PicoClasp crimps. This kit will give you the flexibility to interface with other devices using standard pins (similar to the ones used on JR servo connectors), or it can just be used for development/testing purposes.
Many R/C receivers use a 3-pin connector to output PPM, SBUS or similar. Other devices using the same approach include OSDs and power modules.
2 x 3P-Connector Header 2.54mm
2 x 4P-Connector Header 2.54mm
1 x MRC0284-50mm: 6P-PicoClasp Crimp to 2.54mm Crimp
2 x MRC0284-100mm: 6P-PicoClasp Crimp to 2.54mm Crimp
1 x MRC0284-200mm: 6P-PicoClasp Crimp to 2.54mm Crimp
1 x MRC0284-300mm: 6P-PicoClasp Crimp to 2.54mm Crimp
Harness Assembly
Pico-Clasp Crimp Terminal
Molex Pico-Clasp Connector
Most of the cables are just “pre-crimped” with PicoClaps crimps. They must be inserted into the “connector” with the correct direction of the latch.
