Every week we'll 3D print designs from the community and showcase slicer settings, use cases and of course, Time-lapses!

On this weeks' Desk of Ladyada - we got a mess of prototypes including our Feather M4 Adalogger. We found a few mistakes, we'll chat about them so you can learn from us! We also got a flippy-floppy sensor Stemma QT board for the VEML7700, which comes in two reel flavors. pt has some hacker tunez to show off, and we'll unbox the new UNO MINI Limited Edition!

The Great Search - USB to Serial converter chips

https://www.digikey.com/short/z7bn9vpb

A long time ago, in a galaxy far away, there were computers that came with DE-9 serial ports that would let you read/write 8-bit serial data on two lines. Those days are gone, now we have USB only. Many modern chips have a built in USB native peripheral so you can connect to a computer, but there's still lots of chips that don't! In that case you'll want a converter chip. Lets see what is available in the market and some things to watch out for when spec'ing them.

0:00 Getting started

0:05:16 housekeeping

0:12:52 I found an RP2040 with only 1MB of Flash, so too small for your decision to reserve the first MB for the firmware. Would it be possible to have that has a parameter for board?

0:17:06 look for ‘latest’ branch in tannewt’s github reto to find current work

0:18:05 broadcom changes checked into main !

0:19:10 create a learn guide

0:29:25 ive been trying to get WPE running on the pi zero 2w and that has been almost impossible to figure out ( webkit for embedded )

0:20:44 Broadcom stuff caused people to download 20Gb /submodules /and other tricks to reduce download ( fetch submodules )

0:25:27 git fetch submodules should work most of the time ( except… )

0:26:42 debugging circuitpython should be a guide as well

0:28:58 learn building circuit python page

0:29:30 what is “learn”

0:31:00 Any idea why DAC output in esp32 was responding with three different voltage levels with 10s latency to sent signal instead of Linear 256 levels?

0:31:55 https://ladyada.net/ - adafruit history

0:40:13 learn guide structure

0:42:23 learn ‘feedback’

0:49:00 For what type of measurments are you using oscilloscope most often? - ( logic analyzers )

0:52:35 Create a new guide

0:52:55 choosing a name for the guide - search for other names

0:58:50 Overview page

1:00:20 Can anyone write these learn guides?

1:06:43 Adafruit NeoSlider, do you have any experience with it to rate readings stability?

1:07:12 Installation

1:31:34 Connecting - USB host/device

1:54:20 assume USB host-iness is not yet part of the CirPyRasPiNoOS?

1:55:33 Switch to ESP / ble workflow

1:56:02 Wrap Up

This week's EYE ON NPI is easy-peesy-lemon-squeezy, the simplest way to add LTE cellular data connectivity to your product or project with Blues Wireless Notecard Cellular Modem System-on-Module (https://www.digikey.com/en/product-highlight/b/blues-wireless/notecard-cellular-modem-som).

These M2 cards come with 4 different cellular module types for global coverage on the LTE Cat 1 or Cat 1M (with backup CDMA and GPRS options). Each card slides into one of many different add-on boards that make connectivity to a Feather or Raspberry Pi foolproof.

Blues Wireless' Notecard is a tiny 30 mm x 35 mm SoM device-to-cloud data pump. A Notecard purchase includes 500 MB of data that is usable over 10 years with the ability to top-up as needed. Connectivity is globally available in 136+ countries. The Notecard features an m.2 connector for embedding the user's board. As an embeddable SoM, the Notecard can be used with any microcontroller (MCU) for greenfield and retrofit projects using the user's design or one of Blues Wireless' custom-designed Notecarriers.

With two lines of code, users can send data to the cloud in minutes without complex device registration or provisioning required. With a powerful JSON-based API, the Notecard can be programmed over USB or controlled from the preferred MCU or single-board computer (SBC) using one of Blues Wireless' open-source firmware libraries. Connect from the preferred host to the Notecard using Serial or I2C. The Notecard is designed to work with a cloud service for ingesting and processing device data. Notehub.io provides secure device connectivity, project, and fleet management, as well as simple routing to third-party cloud services. Alternatively, the user can host their device service based on Blues Wireless' open-source reference implementation.

The Notecards use Quectel cellular modules, which are low cost and have been used for many years so they're very reliable. Depending on your location, you may not have LTE coverage yet (or LTE Cat M/M1) so do check your coverage maps and rollout plans - there's versions with GPRS (2G) and CDMA (3G) backup capabilities. The cellular plan itself is handled by Blues and is handled by AT&T, so no external SIM is required - although there is a insert spot for one if desired. Each module is bundled with a 10 year, 500MB cellular plan, which can be customized if needed. 500MB doesn't sound like a lot, but if you're using MQTT for sending data reports, where each packet is only a couple-hundred bytes max, it will last a long time. Check AT&T's coverage map to know which module you'll need to use for your area (https://www.att.com/maps/wireless-coverage.html)

We particularly like the M.2 module design idea - it makes insertion very easy and doesn't allow for flipped boards or bent pins. Swapping out different modules can be done in a post-manufacturing step or as an add-on upgrade situation. It also means as cellular networks are upgraded and retired (which happens every 5~10 years!) the module can be changed over. If you need to source an M2 connector - Digi-Key has tons of those in stock too (https://www.digikey.com/short/zn1q8z), just make sure you get E-key type. These contacts are under a dollar a piece and come on tape-and-reel for easy pick and placing.

The modules are designed for end-use cases. While prototyping you may want to use their handy "Notecarrier" breakout boards (https://www.digikey.com/en/product-highlight/b/blues-wireless/notecarrier). Each one can use any of the Notecards, so just mix and match as desired. There are ones for battery usage, Raspberry Pi HAT, and Feather breakout. (https://blues.io/products/notecarrier/)

And best of all, all of the Blues Wireless Notecards and carriers are in stock right now at Digi-Key! (https://www.digikey.com/en/supplier-centers/blues-wireless) Pick up any combo you need to start prototyping your design immediately. You can get started with Blues' tutorials and code snippets (https://github.com/blues) - they promise you'll be sending data in under 30 minutes. Order today and you can be sending data over cellular by tomorrow morning.
