FlexSEA-Rigid 0.2(B) Connectors

If you are using Rigid 0.1, please refer to the FlexSEA-Rigid 0.1 Connectors page. On v0.2 the expansion connector was flipped to expose the lock (easier to connect/disconnect) and the Strain and Angle connectors have been replaced by Pico-Clasp equivalents instead of PicoBlade. As a result, only one crimp tool is needed.

J4: Expansion

J1 and J2: Strain and Joint Angle

Programming and Debugging

On Rigid 0.2 the programming ports use different connectors. Ex and Re have 0.5mm FFC connectors while Mn, the most often programmed microcontroller, has a more robust 1mm FFC connector. They use different Programming Adapters.

What's different on the B version?

First and foremost, all of the information above is true for both 0.2 and 0.2B. 0.2B is a minor update of 0.2 done at the end of 2019. If you buy an ActPack in 2019 (especially as part of the Open Source Leg project) that's what you will get. The main differences are:

  • New FFC connector for encoder. Legacy connector is still available (both connectors have the same pins and functionality).
  • New FFC connector for external strain gauge. Legacy connector is still available (both connectors have the same pins and functionality).
  • New FFC connector to support External User Interface.

ActPack 0.2B connectors

On the following picture we have an ActPack 0.2B with the cover installed, and a bare Rigid 0.2B (no motor, no cover). When the cover is installed the user cannot access the Reg, UI and Ex connectors. All other connectors are accessible via openings in the cover.

And now a view from the bottom:

Notes for OSL clients:

  • The silkscreen clearly indicates J1, J2 and J4.
  • J1 is for the 1-ch Strain Gauge. It has the same pins as the “SG” FFC connector present on the opposite layer. This is meant to be used with one discrete strain-gauge, not with the 6-ch amplifier.
  • J2 is for the encoder. It has the same pins as the “ENC” FFC connector present on the opposite layer. If you want to use the Dephy AK7452 encoder with a flexible connector, use the ENC FFC connector.
  • J4 is the expansion connector. It does not have an FFC equivalent.
  • To connect the 6-ch amplifier, please refer to this page.
