About the Dynamic Clamp with Teensy PCB

Dynamic Clamp with Teensy is an open source NXP PCB design by nsdesai, published on GitHub. It is a 2-layer board measuring 152.4 × 101.6 mm, with 41 components from 34 distinct parts.

Its main chip is the Teensy3.6, from the NXP family. Other key parts include the AD8032ANZ, TLE2142, TMV_0512D and LM358. By type, the board carries 13 resistors, 6 connectors, 5 ICs, 5 diodes, 5 capacitors and 2 switches.

From the project

A fast, microcontroller-based dynamic clamp system

The system was introduced in this paper: Niraj S. Desai, Richard Gray, and Daniel Johnston. A dynamic clamp on every rig. eNeuro (DOI:10.1523/ENEURO.0250-17.2017).

The website https://optogeneticsandneuralengineeringcore.gitlab.io/dynamicclampsite/ includes detailed instructions on how to assemble and use the system. It includes descriptions of recent updates.

Dynamic Clamp with Teensy: common questions

What microcontroller does the Dynamic Clamp with Teensy use?

The Dynamic Clamp with Teensy is built around the Teensy3.6, from the NXP family.

How big is the Dynamic Clamp with Teensy PCB?

The Dynamic Clamp with Teensy measures 152.4 × 101.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dynamic Clamp with Teensy?

41 components, from 34 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Dynamic Clamp with Teensy design files?

From the nsdesai/dynamic_clamp repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Dynamic Clamp with Teensy design in my own project?

The repository has no license, so all rights stay with nsdesai. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dynamic Clamp with Teensy without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
