Hexabitz Modular Prototyping Platform Enables Wire-Free 3D Electronics Designs (Crowdfunding)

A few years ago, I made a Raspberry Pi case made of perfboard and created some sort of DIY modular 3D electronics design by using the top and sides of the case to also hold electronics components and associated circuitry like a relay, and LEDs. The just launched Hexabitz hexagonal / pentagonal modules are designed to make prototyping easier, and also provide flexibility to create all sort of wire-free (3D) electronics designs with minimal soldering. A little over a dozen of modules are currently on offer, most with an STM32F0 Arm Cortex M0 micro-controller: Modules with built-in MCU 01R00, P01R00 – RGB LED (hexagon / pentagon) with Cree Tri-color (RGB) SMD LED, 4-Pin PLCC H02R10 – Bluetooth/BLE V4 based on Laird BT900-SA + chip antenna, +8 dBm max H04R00 – Audio amplifier, speaker, and headphone jack based on ST TS4990IST 1.2W audio power amplifier, 0.7W, 8 Ohm speaker H05R00 – SPI […]

DirtyJTAG Firmware Convert $2 STM32 “Bluepill” Boards or ST-Link V2 Clones into JTAG Adapters

DirtyJTAG is a JTAG adapter firmware for cheap STM32 boards like BluePill or equally inexpensive ST-Link V2 clones that was developed to create an alternative to the cheap – but now obsolete – LPT Wiggler cables, and more expensive USB JTAG probes. You’ll find the source, and documentation on Github. First, you’ll need to flash the firmware using the DFU method or an SWD programmer (for ST-Link) or USB to TLL debug board (for STM32 dev boards), before making the connection to the target board as shown below (for Bluepill). STM32 JTAG PA0 TDI PA1 TDO PA2 TCK PA3 TMS PA4 TRST PA5 SRST You can then use mainline UrJTAG for your newly flashed JTAG adapter. If you prefer OpenOCD, it might eventually be possible to use Versaloon firmware instead on STM32 Bluepill board. Thanks to Zoobab for the tip.

Avnet Silica NB-IoT Sensor Shield Works with mbed OS 5, STM32 Nucleo Board

If for some reasons, none of the many NB-IoT boards launched recently suit your needs, there’s yet another option with Avnet Silica NB-IoT sensor shield, that supports – despite the name – also supports LTE Cat M1 (eMTC) beside NB-IoT (LTE Cat NB1), and comes with Arduino headers, as well as a Pmod connector. The board relies on Quectel BG96 module, and can be controlled with Arm mbed OS 5 when connected to STM32 Nucleo board. NB-IoT Sensor Shield specifications: Cellular Module – Quectel BG96 LPWA Module Multi Modes: Cat.M1, Cat.NB1, EGPRS Global bands Cat M1/NB1: B1 B2 B3 B4 B5 B8 B12 B13 B18 B19 B20 B26 B28 B39 (B39 for Cat M1 only) EGPRS: 850/900/1800/1900 MHz Voice Over LTE support (M1 only) – PCM digital audio interface SIM card holder (also optional embedded SIM) Optional GNSS – GPS, GLONASS, BeiDou/Compass, Galileo, QZSS Expansion – Arduino headers, Pmod connector […]

STMicro Introduces Two STM32 Discovery Kits with 2G/3G or 4G LTE-IoT Cat M1/NB1 Connectivity

Embedded World 2018 trade fair will take place on on take place on February 27 – March 1 in Nuremberg, Germany, and we’re starting to see some company announce new products and solutions for the embedded market. STMicro has just announced their showcase their very first cellular development kits at the event, based on a display-less variant on their 32L496GDISCOVERY Discovery board with cellular add-on boards: P-L496G-CELL01 Discovery kit with with a 2G/3G modem P-L496G-CELL02 Discovery kit with with an LTE-IoT Cat M1 (eMTC) / NB1 (NB-IoT) / 2G model Now the company has not started designed their own cellular modem, but instead relying on QUECTEL modems. Both kits share most of the same specifications: MCU – STMicro STM32L496AGI6 Arm Cortex M4F MCU@ 80 MHz with 1 MB Flash, 320 KB RAM in a UFBGA169 package On-board memory – 8 Mbit PSRAM On-board + external storage – 32 KB I2 […]

BigClown is a Battery Powered Modular Wireless IoT Kit for Makers (Crowdfunding)

BigClown IoT Kit is designed to be as easy to use as building a castle from LEGO bricks or an IKEA cabinet. The open source kit is comprised of a coreboard module with STMicro STM32L0 Cortex M0+ micro-controller, and a sub GHZ (868/915MHz) radio for wireless communication, that accepts one or more compatible modules (currently ~30 different options), and communicate to a gateway such as Raspberry Pi or Turris Omnia where you’d connect BigClown RF USB dongle, although it’s also possible to include a Sigfox module for communication, and , LoRa & NB-IoT module appear to be planned. That’s for the hardware…The kit then connects to your chosen gateway via MQTT, which in turns accesses cloud services such as Ubidots, Microsoft Azure IoT, AWS, IFTTT, etc… , and you can monitor the data or control the kit through a web based dashboard or your own application. Core Module specifications: MCU […]

Pulurobot is a Low Cost Open Source Raspberry Pi based Load Carrying Autonomous Robot

Earlier today I wrote about FOSDEM 2018 schedule, and among the various talks I selected for my virtual schedule was “How to build an autonomous robot for less than 2K€”. Some excerpt from the abstract including a short description of the project, and its “open-sourceness”: PULUrobot solves the autonomous mobile robotics complexity issue without expensive parts, without compromise. By fearless integration and from-scratch design, our platform can do SLAM, avoid obstacles, feed itself, and carry payload over 100kg, for less than 2,000 EUR. Application ecosystem can be born around it, as we offer a ready-made Open Source (GPLv2) solution in a tightly coupled HW-SW codesign. So I decided to have a closer at this project, which can be used as a robot maid/helper of sort, and other applications. The robot was made by a brand new (July 2017) startup called Pulu Robotics Oy and based in Finland. They have three […]

AcSiP S76G/S78G SiPs Integrate LoRa, GPS, and MCU into a Single 1.3×1.1 cm Package

LoRa has been combined with GPS in several products such as Rakwireless RAK811 LoRa tracker board, or Dragino LoRa/GPS HAT board among others, with all designed for far based on a LoRa module, plus a GPS module. LoRa GPS tracker will soon even smaller as AcSiP has developed S76G and S78G systems-in-package (SiP) that combine LoRa, GPS and an MCU into a single 1.1 x 1.3cm package. The two new modules are not listed on the company’s IoT-LoRa products page yet, but they appear to be an evolution of their S76S / S78S LoRa + MCU SiP released in 2016, so the new modules should have the following features: MCU – STMicro STM32L073x Arm Cortex M0+ MCU with up to 192 KB of Flash memory and 20 KB of RAM LoRa AcSiP S76G – Semtech SX1276 supporting global 868 MHz or 915 MHz ISM-Bands. AcSiP S78G – Semtech SX1278 supporting […]
