LoRaWAN no code ESP32-S3 development platform offers Arduino MKR, MikroBus, FeatherWing, and Grove expansion (Crowdfunding)

Sheffield-based IoT company, inx-systems has developed a programmable LoRaWAN IoT module and a development breakout board that integrates with Arduino MKR, Adafruit FeatherWing, Grove, and mikroBUS shields. The module is powered by an ESP32-S3 microcontroller which comes preloaded with inx’s no-code LoRaWAN software development platform, Lucid. The WAN-4-ALL module has built-in Wi-Fi, Bluetooth, and LoRaWAN connectivity via the ESP32-S3 microcontroller and Seeed Studio Wio-E5 module. This makes the module suitable for short-range, medium-range, and long-range IoT applications such as remote monitoring, home automation, industrial control, and smart agriculture. We have covered other LoRaWAN development platforms such as SB Component’s RAKWireless-based products, Particle’s multi-radio devices, and the UnPhone. The WAN-4-ALL module differentiates itself with the preloaded no-code LoRaWAN development environment and multiple connectivity options. WAN-4-ALL module specifications: SoC – Espressif Systems ESP32-S3 dual-core microcontroller @ 240MHz with Wi-Fi 4, Bluetooth LE 5 LoRaWAN Module – Seeed Studio Wio-E5 Module based on […]

Microchip PIC32MZ-W1 is a 32-bit MIPS WiFi MCU with 60+ GPIO, USB, CAN Bus, Ethernet, and more

PIC32MZ W1 and WFI32 2.0 Curiosity Board

Microchip recently released the PIC32MZ-W1 wireless MCU along with 20 other WiFi parts, including WiFi MCUs, link controllers, network controllers, and plug-and-play modules. Among them, the PIC32MZ-W1 wireless MCU is the most interesting because of its 32-bit MIPS microAptiv M-class core running at up to 200MHz, advanced hardware security features, and integrated Microchip Trust Platform for secure cloud authentication. Over the years ESP32 MCUs have become the go-to choice for wireless applications. Still, one problem we always have with ESP32 SoCs is their limited GPIO option due to their strapped-out pin structures. But this new MCU has over 60 GPIO pins to work with along with Ethernet MAC, USB, CAN Bus, CANFD, SPI, I2C, SQI, UART, ADC, JTAG, and more. PIC32MZ-W1 wireless MCU specifications MCU MIPS32 M-Class core clocked at 200 MHz 16KB I-Cache, 16KB D-Cache microMIPS mode (up to 35% smaller code size) DSP extensions (4x 64-bit accumulators, single-cycle […]

ELLO LC1 – A 2mm thin DIY “computer” based on Microchip PIC18 8-bit MCU

We often write about business card or credit card-sized boards, but it’s only true for 2D dimensions, as most boards are over a centimeter thick, with possibly the thinnest we’ve covered being the Khadas Edge2 SBC that’s just 7mm thick. So Kn/vD took it upon himself to build a DIY computer that was really about the size of a credit card, and came up with the ELLO LC1 based on a Microchip PIC18 8-bit microcontroller, featuring an integrated display and keyboard, and powered by a coin-cell battery. It’s just 2mm thin. ELLO LC1 specifications: MCU – Microchip PIC18 (PIC18F47Q83-I/PT) 8-bit microcontroller with 13KB RAM and 128KB flash, out of which 64KB are reserved as user file storage Display – 20×4 character text panel (Display Visions EADOGM204N) Keyboard – 48x touch panels on the PCB Expansion – 12-pin unpopulated header for debugging (ICSP) and GPIO expansion Misc – Power button Power […]
