Hi there,

I've said it before and I'll probably have to say it again: we don't talk enough about what it means for an IoT engineer to scale a product. It's fun to brainstorm prototype concepts and get up and running with Notecard and Notehub, but sometimes the enjoyment wears off when we start to scale. That's why we are partnering with Ubidots and Sento to present Scalable IoT for Developers — a webinar where we'll talk about what breaks, what may blindside you, and what you wish someone had told you...before you deployed.

P.S. Take the shortest survey ever to let us know how we are doing. 💙

Notecard Firmware v9.1.1

Following up on our latest LTS release, the v9.1.1 Developer release of Notecard firmware is now available. The new version includes support for variable-length numeric arrays in Note templates, numerous reliability and efficiency improvements, and a variety of bug fixes.

Blues University

A keen eye on the Blues blog will have noticed a mysterious "Blues University" author appear over the past months. Well, we now have a critical mass of instructional articles ready to help new IoT developers understand some core technical concepts. Standout articles include Understanding Sensor Interfaces - UART, I2C, SPI and CAN and Power Management and Energy Efficiency in Embedded Systems.

Project Spotlight

This month we are highlighting a handful of projects that use Notecard in a novel way, specifically by helping the visually impaired navigate indoors and outdoors: A Smart Hiking Stick for the Visually Impaired 🥾, Dynamic Vision Assist 🚶, SafeSteps: Enhancing Outdoor Mobility 🏕️, and MovingFan: Enhancing Comfort and Safety ☺️.
