Repository
This repository combines hardware and software files for my power consumption projects.
Hardware
Hardware files for :
- NanoCurrents, a way to amplify easily with a small board currents from the nA range, using a INA211 shunt monitor and multiple shunt footprint to use.
- NanoCurrents4USB, a way to monitor power consumption on an USB bus, with an integrated STM32L011F4Px microcontroller to measure and send measures via UART. Based on an INA211 shunt monitor, and a basic voltage buffer (ratio 1/2).
- NanoCurrentsSupply, a way to supply three differents voltage to a target and monitor the power consumption (INA240) with the integrated ADC (ADS1015).
Software
Software for NanoCurrents4USB :
- Firmware to run on STM32L011F4Px : acquire data and send it via UART.
- Python script to get UART from COM port on computer and display data in real time.
Doc
Interesting documentation for power consumption and side power analysis:

Questions
How big is the NanoCurrentsSupply PCB?
It measures 40.8 × 43.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NanoCurrentsSupply use?
51 parts, built around the LMV358, ADS1015IDGS, INA240A1D and LP2980-ADJDBV. 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 NanoCurrentsSupply KiCad files?
From the frchp/nano-currents repository on GitHub, at the commit this page was made from: the board is hw/NanoCurrentsSupply/NanoCurrentsSupply.kicad_pcb and its schematic hw/NanoCurrents/v1/NanoCurrents.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NanoCurrentsSupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask frchp before reusing the design.
