[Above: 3+ years of NeuroBytes evolution. The new boards have different connectors, different microcontrollers, different graphics, different LEDs, different communication protocols, and ... well, different just-about-everthing. Below: the current NeuroBytes ecosystem as rendered from the original PCB designs, all of which are in production. Left to Right: Interneuron, Tonic Neuron, Motor Neuron, Touch Sensory Neuron, Pressure Sensory Neuron, Rod Photoreceptor, Battery Pack. Accessories and other prototypes not shown...]
NeuroBytes® are open-source electronic neuron simulators designed to help students understand basic neuroscience. Each module can be freely connected with others to form complex and biologically representative neural networks. On-board reverse-mounted RGB LEDs indicate current state: excited, inhibited, firing, learning, etc. The boards are based on the STM32L0 ARM Cortex M0+ microcontroller and the libopencm3 hardware library, and communicate via a novel board-to-board networking protocol that allows central data collection and global message broadcasting.

Since its inception in mid-2012 and hardware development starting in February of 2014, this project has gone through many iterations and spawned the formation of NeuroTinker, LLC, a for-profit company primarily funded via Phase I and Phase II SBIR grants from the National Science Foundation. Our six NeuroBytes kits -- the Skin Kit, the Eye Kit, the Knee Jerk Reflex Kit, the NeuroBuggy Kit, the Advanced NID Kit, and the Standalone NID KIt -- are currently in production and are scheduled to ship to our Kickstarter backers and other early adopters fall 2018.
Open Source Hardware
NeuroBytes is Open Source Hardware, as defined by OSHWA and standardized under their Certification Program (US000024 for the ATtiny88-based v0.91 boards, US0108 through US0115 for the current STM32L0 devices). Our design files (C code for firmware and KiCAD files for hardware) are released under the terms of CC-BY-SA 4.0 as detailed in our license file.
NeuroTinker GitHub Repositories. The firmware and hardware files for this project are released under CC-BY-SA 4.0 and the latest version will always live in the linked GitHub organization. Individual boards and support items are listed under individual repos (Interneuron, Motor Neuron, etc).
NeuroTinker company site. This is where we share additional information related to the NeuroBytes product line, such as operating instructions, kit purchase links, and social media account info. We have a public forum on the site that sees occasional use, and a spot to sign up for infrequent email newsletters that make every effort to consolidate important info into one location.
This project page. Yes, the project page you are currently reading. New project logs will appear somewhat frequently and tend to provide a good up-to-the-minute record of technical challenges and developments; conversely, if you want an exhaustive history of NeuroBytes you can start at the beginning. We've had a few great conversations in the log page comment sections (along with the main comment section), so don't hesitate to provide your input.
