Technical application notes for hardware and software designs and best-practices.

• AN001 Basic SoM Design is a simple SoM base board. Like a Boron it can be powered by LiPo battery, USB, or an external DC supply. It includes: RGB LED, bq24195 PMIC, MAX17043 Fuel Gauge, USB Connector, LiPo Connector (JST-PH), and M.2 SoM Connector.

• AN002-Device-Powerdown shows how to have an Electron, E Series, or Boron gracefully power down under battery power when the power supply is disconnected then automatically power up when restored. This can be useful in automotive applications or devices powered by a switch in mains power applications.
• AN003 Interpreting Cloud Debug shows how to interpret cloud debugging logs to troubleshoot various common issues.
• AN004 Interpreting Cloud Debug-2 is a deep dive into interpreting cloud debug logs and cross-referencing the AT command guide for the u-blox modem.
