New ESP32-S2 modules: ESP32-S2-MINI

Espressif’s ESP32-S2-MINI series of modules currently consists of ESP32-S2-MINI-1 and ESP32-S2-MINI-1U , which are two powerful, generic Wi-Fi MCU modules with a rich set of peripherals. They are an ideal choice for a wide variety of application scenarios relating to the Internet of Things, wearable electronics and smart home.

ESP32-S2-MINI-1 comes with a PCB antenna, whereas ESP32-S2-MINI-1U with an IPEX antenna. They both feature a 4-MB embedded SPI flash.

At the core of the ESP32-S2-MINI modules is ESP32-S2FH4 , an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz. This chip has a low-power co-processor that can be used instead of the CPU, in order to save power while performing tasks that do not require much computing power, such as the monitoring of peripherals. ESP32-S2FH4 has up to 43 GPIOs and integrates various peripherals, such as SPI, I2S, UART, I2C, LED PWM, LCD, camera interface, ADC, DAC, touch sensor and temperature sensor. ESP32-S2FH4 also includes a full-speed USB On-The-Go (OTG) interface which enables USB communication in any place, at any time.

Will go into mass production end of 2020.

This, which leads to the PDF (upside down but easily rotated) which leads to the comment that the UK already has a code of conduct - off to Google that now.

Edit, here’s the UK one:

Yes, I recall ref to the new code (and fact some big boys signed up) was captured and ref’d in the Library (v6 or 7?) back in Oct '18 - good to have it resurfaced as likely now buried in history, though it was felt by some (inc. beery discussions at the UK Norwich TTN Conf!) that it was a puff piece with people ‘signing up’ for PR value at the time :wink:

You will find similar materials and references to related secure systems/design here including a consultation on potential new regulations (closing this weekend!):

The broadsheets and e.g. the register covered at the time:

What goes around comes around…

The history here is Cellnex bought the Telecoms biz of Arquiva just a year ago, to add to the deal they had earlier done to operate and promote 220 high towers previously run by BT. Arquiva of course was the original local UK SNO - (Sigfox netwrok Operator) - before fiscal pressures forces the tower/telecoms sell of in a deal worth approx £2Bn (enterprise value). Arquiva had to slow down/reduce kill of their Sigfox investment which subsequently led to WND setting up locally instead…

… now, through the deal with Everynet, they are supporting LoRaWAN deployment… :wink:

IoT Network Companies Have Cracked Their Chicken-and-Egg Problem

In case anyone missed it last week The RPi Foundation launched an integrated system based on customised RPi4 pcb derivative embedded in keyboard and also available as a kit… I couldnt resist and ordered :slight_smile: 2 arrived Friday (1 went awol :frowning: ) now looking at use cases around dev, IoT & TTN etc. as well as for kids education and learning… available or on backlog at usual RPi resellers…e.g.

Latest Semtech Results - Wireless & Sensor Group sales up 32% on strong LoRa contribution :slight_smile:

LoRa Alliance introduces QR code standard for rapid, zero touch device onboarding. LoRa Alliance members to have specific ID’s for embedding in the code.

@wienkegiezeman @johan @laurens will TTN/Community have access to an ID code (vs TTI?) that we can use at scale to rapidly onboard TTN based devices? :thinking:

Specification/Requirements Doc. TR005:-


While good to see this being released, I would have thought the standard would have been made extensible and future proofed by using a tagged method (eg something like Json or similar).

Also a little surprised by the small number of contributors, would have thought quite a few others would have participated.

Yeah the QR code spec is finally here, and it will drastically improve device onboarding.

Today I’m hosting a webinar for device makers, and I’d love to see community members there too, as they are building community products or contemplating about going commercial with their work. Please sign up here:

The webinar will mostly be around the device repository:

As for @Jeff-UK’s question on whether the community can make use of TTN’s vendor ID (428) still needs to be decided. It looks like it doesn’t come with responsibilities, certification requirements, etc, so it doesn’t seem like there are many problems with doing that.

JSON doesn’t fit; QR codes should be as small as possible so the aim was to reduce the number of characters. As for extensions, there’s the Proprietary extensions, see document. Device makers can put anything in there.

This doesn’t say anything really. Contribution, i.e. the listed names on the spec, is different from participation. In the LoRa Alliance, unless you submit a Word diff in a committee call in a specific format, you’re not a listed contributor of the specs.

Thanks, I’ll have a closer look.
