README
readme.mdLora-based environmental monitor
- intended for monitoring collection items in musea. Other applications are possible but the unit is currently designed for indoor use only
- monitors temperature, relative humidity, VOC gasses, barometric pressure, light intensity and others
- BME680 and TSL25911 sensors are built in, other can be added through I2C or UART
- runs on a single cell LiFePO4 battery. Battery-charger from USB-C port included
- Wio-E5 LoRa module from www.seeedstudio.com. This contains an STM32WLE processor combined with Semtech SX126X radio. The firmware runs directly on the STM32. More info on this Wio-E5 : https://www.seeedstudio.com/LoRa-E5-Wireless-Module-p-4745.html
- 128 KByte of onboard EEPROM allows to buffer sensor-readings when network is unavailable.
- ePaper display allows to identify the device, and read status from the display, while still being ultra low power.

Questions
How big is the MuMo v2-Node PCB?
It measures 52 × 56.6 mm and has 2 copper layers, 1.64 mm thick.
What parts does the MuMo v2-Node use?
79 parts, built around the LORA-E5-HF, BME680, CP2102N-A02-GQFN24R and TSL25911FN. 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 MuMo v2-Node KiCad files?
From the Strooom/MuMo-V2-Node-PCB repository on GitHub, at the commit this page was made from: the board is kicadProject/MuMo-v2-Node.kicad_pcb and its schematic kicadProject/MuMo-v2-Node.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MuMo v2-Node design in my own project?
Its repository states no licence, so its author keeps all rights: ask Strooom before reusing the design.
