This repo contains the hardware design files of our elastic node hardware for deploying deep learning architectures on embedded hardware.
ENv6 - Elastic Node v6
Still in progress
ENv5 - Elastic Node v5
The 5th generation of Elastic node is designed based on the 4th version, but with some improvements. The main improvements are:
- Using Cortex-M0 MCU instead of AVR 8-bit MCU, to gain more performance and lower power consumption.
- Using SPI as the communication interface between MCU and the FPGA to save more IO pins.
- Simplify the power supply circuit to reduce the space and improve reliability.
- Adding an energy meter chip to ease the energy measurement.
- Optimize the PCB layout to reduce the PCB size.
Before you start using the ENv5, please read the following documents accordingly:
Troubleshooting
- When you notice the esp32 is not responding to the RP2040, you can apply the pre-build firmware to test.
- some descriptions about the behavior of the test are available here.

Questions
How big is the Elasticnode tiny PCB?
It measures 34 × 34 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Elasticnode tiny use?
125 parts, built around the RP2040, W25Q16JVUXIQ, PAC1934-I/JQ and JUMPER3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Elasticnode tiny KiCad files?
From the es-ude/elasticai.hardware repository on GitHub, at the commit this page was made from: the board is v5/tiny/elasticnode_tiny.kicad_pcb and its schematic measurement/mxo_offset_full/MXO_Offset_Generator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Elasticnode tiny design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
