As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]
Ai Thinker enters the NB-IoT LPWAN market with EC-01 modules (Sponsored)
As we all know, 2G and 3G cellular networks are gradually being sunset, and NB-IoT has been formally incorporated into 3GPP standards. The LPWAN industry has ushered in new development opportunities for the Internet of Things market. Ai-Thinker has recently released three NB-IoT series modules: EC-01/EC-01F/EC-01G. The NB-IoT series modules are equipped with the EC616S chip platform, which is an ultra-low-cost, ultra-low power, ultra-high integration NB-IoT SOC chip, fully supporting the 3GPP R13/R14 NB-IoT standards with up to 159 kbps uplink. What are the benefits of the new modules? Better signal, more spectrum Better performance (equipped with EC616S) Ultra-low power consumption, stable and reliable connectivity I/O expansion, feature-rich module Check out the comparison table between AI Thinker NB-IoT modules part of the EC-01 family below. Ai-Thinker NB-IoT series modules adopt an SMD package that is convenient for mass production at the factory, and can use AOI to do the SMT […]
Eigencomm EC616/EC616S SoC supports Cat-NB2 cellular IoT
Eigencomm EC616/EC616S are Cortex-M3 microcontrollers supporting the 3GPP R13/R14 NB-IoT standard, with 3GPP R14 notably introducing the newer LTE Cat-NB2 standard allowing higher bitrates up to 127 kbps downlink, and up to 159 kbps uplink, and OTDOA and E-CID positioning methods. Both EC616 and EC616S are virtually identical, but the EC616S comes with fewer GPIOs and is designed for the lowest possible BoM cost for modules as small as 10×10 mm. Both target similar IoT applications such as wireless meter reading, smoke detection, smart street lights, smart logistics, asset tracking, smart fire monitoring, smart parking, smart home, wearable devices, industry 4.0, smart agriculture, and others.

Blues Wireless Swan board adds castellated holes to Adafruit Feather form factor
We’ve often written about Adafruit Feather-compatible boards in the past, but Blues Wireless Swan board is a little different, as the STM32L4-based board comes with castellated holes instead of just through holes which allows the board to expose up to 55 GPIOs, or 36 more pins than a traditional feather-compatible board. The company also introduced the “Feather Starter Kit for Swan” that enables the board to work with the company’s Notecard LTE Cat-M/NB-IoT M.2 modem that ships with 10-year (up to 500MB) of IoT connectivity, as well as GPS/GNSS connectivity.
