It is interested but unfortunately the choice of pads they chose to expose prevents access to half of the SERCOM ports. The SERCOM remapping capability of the SAMD21 is one of its most powerful features of this processor but of little value with this module.
Looking at target markets (in home/local neighbourhood) and reduced sensitivity c/w prior products suggests it may not support the higher SF’s (and may hence be smaller & cheaper due to reduced codec/memory demands?)…need to go check the datasheets!
Latest L-A Regional Parameters - cleared just before TTC2020 Amsterdam and triggered several supplier discussions wrt some of the new countries covered by e.g. amended AS923 sub plans
RP2-1.0.1 LoRaWAN® Regional Parameters
RP002-1.0.1 has been released and includes two significant changes. First, the channel plan for AS923 has been augmented to support a large number of additional countries which support the characteristics of the band albeit in slightly different frequency ranges. The base plan remains unchanged, but we have added the ability to define a frequency offset which shifts the entire plan in frequency to accommodate these new regions. AS923-1 represents the original AS923 plan; AS923-2 shifts the plan down 1.8MHz to support Indonesia and Viet Nam ; AS923-3 shifts the plan down 6.6MHz to support Philippines , Cuba as well as many European and EU-style regulatory domain countries. Secondly, CN470-510 was updated in light of coming regulation changes impacting this band. Specifically a dwell time limit was introduced and channel bandwidth restrictions were relaxed.

Asset loss and theft prevention
In 2020, we will be launching 4 new chips, covering different segments of the market, price points and performance. Our latest chips feature our new radio architecture that has lower power consumption while maintaining the same -40°C~125°C performance. The peripherals have been upgraded with highly sensitive capacitive touch IO’s. Capacitive touch controls are now a staple of user interfaces because they are cost efficient; certain functions such as slider controls are better supported with capacitive touch than with analog implementations.
HEADS UP! Anyone using Lets Encrypt Certs ?- be advised in case you are one of the 3M+! (TTN/TTI Admins?)
Updated to reflect todays (5th March) decision to hold off process given ~half done and potential impact to stability of sections of the internet/www infrastructure…and fact LE Certs die/renew every 90 days by default hence many will eventually fade…
Latest US network announcement… with added crypto mining on the gateway?! WTF!!!
With Helium’s own open-sourced blockchain technology, individuals are incentivized to deploy Helium Hotspots, which simultaneously mine cryptocurrency and provide LoRaWAN network coverage for hundreds of square miles
