ESP32-S3 board features 2.8-inch display, Blackberry-like keyboard, and optional LoRaWAN connectivity

LILYGO T-Deck is a development kit with an ESP32-S3 WiFi and BLE module, a 2.8-inch display with touchscreen support, a Blackberry-like keyboard based on ESP32-S3, and optional LoRaWAN connectivity through an SX1262 LoRa module. It looks ideal for text-based messaging, but the devkit also includes two microphones and a speaker so audio communication must be possible. Other features include a MicroSD card slot, a Grove connector (UART) for expansion, and support for a LiPo battery with USB charging. LILYGO T-Deck specifications: ESP32-S3-WROOM-1 wireless module SoC –  ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash PCB antenna Storage – MicroSD card slot Display – 2.8-inch IPS display with 320×240 resolution; ST7789 SPI display controller Audio – Built-in speaker using MAX98357A amplifier, 2x MEMS microphones Wireless 2.4 GHz 802.11n WiFi […]

XCVR LoRa-based IoT development board & reference design features SX1261, SX1262, or LLCC68 chip

Semtech Corporation and “Connected Development” engineering firm have launched the XCVR development board and reference design based on Sentech SX1261, SX1262, or LLCC68 transceivers with the last one targeting Smart Home applications. The XCVR development board is actually an Arduino shield that’s been tested with Nordic nRF52840-DK board, but should work with most boards equipped with Arduino Uno headers. It can be used for the design of LPWAN IoT applications using SX1262x transceivers such as smart meters, industrial controllers, asset tracking, building automation, smart agriculture, etc… while the LLCC68 model is more useful for Smart Home applications and consumer devices. XCVR shield specifications and features: LoRa and FSK Modem Programmable bit rate up to 62.5 kbps LoRa and 300 kbps FSK External antenna Link budget 163 dB maximum for SX1261 170 dB maximum for SX1262 configurations. Tx Power +15 dBm high-efficiency PA for SX1261 +22 dBm or +15 dBm high-efficiency […]

433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors

CNXSoft: This is a guest post by Florian Robert (1technophile) of the OpenMQTTGateway project about using a 433 MHz LoRa transceiver on an ESP32 board for home automation, specifically to talk to 433 MHz sensors Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car. If we want to be specific, we can talk about the different radio frequencies (433 MHz, 915MHz, 868MHz, 315MHz, or 350MHz) and signal modulations OOK, ASK, FSK that we encounter behind the keyword 433MHz.

ESP32 board supports 2.4Ghz LoRa with SX1280 RF transceiver

We’ve seen plenty of ESP32 LoRa boards with the traditional 433 MHz, 868 MHz, or 915MHz frequencies, but I think LilyGO LoRa V1.8 (aka T3 V1.8) is the first ESP32 board that integrates a Semtech SX1280 transceiver for the 2.4GHz LoRa standard used for global coverage, notably maritime applications, and ranging. The ESP32 & SX1280 board also offers 26 pins for expansion, a microSD card for data storage, a 2-pin connector for batteries, a 0.96-inch OLED for information display, and comes with a 3D antenna and u.FL connector for WiFi and Bluetooth, and an SMA antenna for LoRa connectivity. LilyGO LoRa/T3 V1.8 specifications: SoC – Espressif ESP32 dual-core Xtensa LX6 processor with 2.4 GHz WiFi 4 and Bluetooth 4.2 Storage – 4MB SPI flash, microSD card slot Display – 0.96-inch OLED display with 128×64 resolution (SSD1306 I2C driver) Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps +  Bluetooth 4.2 […]
