Maia ESP32-S2 Development Board Features Micro USB OTG Port, Prototyping Area

One of the advantages of the new ESP32-S2 processor is that it offers a USB OTG interface. So far few boards took advantage of the extra interface, and one of the rare ones is Cucumber ESP32-S2 board with a USB-C OTG port. There’s another option with a slightly unusual form factor thanks to Stetel Things’ Maia ESP32-S2 development board with the typical USB-C port for power and debugging, plus a micro USB OTG port, and a small prototyping area. Maia ESP32-S2 development board specifications: SoC – Espressif System ESP32-S2 single-core LX7 processor at up to 240 MHz with an ultra-low-power (ULP) RISC-V CPU, 320KB RAM Storage – 4MB flash Connectivity – 802.11b/g/n WiFi 4 with on-board PCB antenna USB 1x Micro USB OTG port for data and power 1x USB-C port for programming (virtual UART) and power Expansion 24-pin I/O header “Playground” prototyping area with 4x 18 through holes including […]

TASMOTA Now Supports ESP32 Targets including some Ethernet and Camera Boards

TASMOTA now supports ESP32. The open-source firmware was initially designed for ESP8266 and ESP8285 based Sonoff home automation devices providing an alternative to eWelink firmware with support for MQTT protocol allowing integration with home automation frameworks like Domoticz or openHAB. It has since then expanded to support hardware from various brands, but until recently you were still limited to products with ESP8266 or ESP8285, and the good news is that TASMOTA has now gotten experimental support for ESP32 boards and products such as TTGO T-Camera. You’ll find basic documentation and well as Tasmota ESP32 (aka Tasmota32) firmware files for LilyGO TTGO T-Camera board, displays, and I2C sensor on Tasmota Github.io website. The ESP32 port is based on Jörg Schüler-Maroldt’s work. PuceBacoon also found other ESP32 boards in the source code including Olimex ESP32-PoE board in xdrv_82_ethernet.ino file and “AI Thinker” cameras in xdrv_81_webcam.ino. If you’d like to give it a […]

ESP32 Board Features mini PCIe & SIM Card Sockets for 4G LTE Connectivity

ESP32 SIM Card T-PCIe Board Pinout Diagram

LilyGO has launched yet another ESP32 WiFi & Bluetooth IoT board. As its name implies, TTGO-T-PCIe board includes a mini PCIe socket that coupled with a SIM card socket allowing users to insert a 4G LTE mPCIe card to add cellular connectivity. The company also offers optional SIM7000 2G or SIM7600 4G LTE modems that come with LTE and GPS antennas. You should probably be able to add other cellular mini PCiE, as well as other wireless mPCIe modems for LoRa, Satellite communication, etc… (Finally most probably not) TTGO-T-PCIe board specifications: Wireless module – ESP32-WROVER-B with ESP32 dual-core wireless SoC with 520KB SRAM, WiFi and Bluetooth with on-board antenna, as well as 4MB flash, and 8MB PSRAM Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps (ESP32) Bluetooth 5.1 LE (ESP32) Optional wireless cards via mPCIe socket (I2C and UART), SIM card slot for 2G and 4G LTE cellular networking […]

Particle Takes Pre-orders for its Cellular Tracking SoM, Evaluation Kit, and Tracker One Asset Tracker

Earlier this year, Particle announced its Tracking System turnkey solution comprised of Tracker SoM LTE IoT module, Tracker One asset tracker with enclosure, as well as Particle Tracking Services software suite with geolocation services, fleet management, and an open device firmware application framework to integrate with off-the-shelf IoT sensors and enable OTA firmware updates. The hardware devices were expected for June/July 2020, and the company has now started to take pre-orders for Tracker SoM, its evaluation kit, and Tracker One for respectively $79.99, $99.99, and $127.99. Shipping is expected to start in August 2020. We already covered Tracker SoM in our initial article with the full specifications, but basically, it’s a Nordic Semiconductor nRF52840 powered module with 8MB flash, ESP32 for WiFI (including support for indoor location), U-blox Neo-M8U GNSS module, and a choice of Quectel BG96 LTE CAT M1 module for the US or Quectel EG91-X CAT 1 module […]

TTGO T-Watch K210 / K210 AIOT Watches Perform Face Detection with Kendryte K210 RISC-V Processor, ESP32 WiSoC

After covering ESP32 based TTGO T-Watch-2020 programmable watch last month, I noticed LilyGO launched “TTGO T-Watch K210 AIOT” watch with Kendryte K210 RISC-V AI SoC and a camera for face detection and recognition, and while searching for information, I discovered another apparently similar “TTGO T-Watch K210“. But let’s look into the specifications to find out what the differences are. I first came across TTGO T-Watch K210 AIOT, so let’s have a look at some preliminary specifications for this model: AI Processor – Kendryte K210 RISC-V Dualcore 64bit with FPU with 8MB SRAM Storage – 16MB QSPI flash, MicroSD card socket Display I/F – FPC connect for external display (not included) Camera – 2MP OV2640 sensor Audio – MAX98357A Audio codec; CVSD & SBC audio encoding Connectivity – 2.4 GHz 802.11b/g/n WiFi 4 up to 150 Mbps, Bluetooth 4.2 BR/EDR and BLE Debugging – USB-C port via CP2104 Expansion UART, SPI, […]
