TTGO T-Higrow is a WiFi & Bluetooth connected soil temperature & moisture sensor

LilyGO WiFI Bluetooth soil-sensor kit battery case

LilyGO has made plenty of ESP32 “TTGO” boards with various features be it PoE, battery support, OLED display, cellular connectivity, and even a devkit in watch form factor. The latest product from the company specifically targets smart farming/gardening as TTGO T-Higrow embeds either DHT11 temperature and humidity sensor or BME280 temperature, humidity, and barometric sensor to report soil temperature and moisture over Bluetooth or WiFi. It can also come as a kit with a battery and a 3D printed enclosure. TTGO T-Higrow board specifications: SoC – Espressif Systems ESP32 dual-core LX6 processor @ up to 240 MHz with 520 LB SRAM, Wi-Fi & Bluetooth Storage – 4MB QSPI flash Wireless 2.4 GHz 802.11b/g/n WiFi 4 up to 150 Mbps Bluetooth 4.2 BR/EDR and BLE Sensors Option 1 – DHT11 temperature and humidity sensor Option 2 – BME280 temperature, humidity, and barometric sensor Expansion – 2x 12-pin through holes with UART, […]

$6 WT32-ETH01 is a Tiny ESP32 board with Ethernet

Espressif Systems ESP32 processor supports WiFi, Bluetooth, and Ethernet connectivity. There are only a few boards coming with an Ethernet RJ45 jack out of the box including esp32MX-E ESP32 board, TTGO T-Internet-POE, and Olimex ESP32-Gateway board among others. Those boards are fine, but they sell for $16 and up, so if you’d like a cheaper and tinier ESP32 board with Ethernet, Wireless Tag WT32-ETH01 may be an option for projects not requiring PoE support. WT32-ETH01 board specifications: Wireless Module – Wireless Tag WT32-S1 based on ESP32 dual-core WiSoC with 4MB flash, on-board antenna Connectivity 10/100M Ethernet via LAN8720A transceiver 2.4 GHz 802.11b/g/n WiFi 4 up to 150 Mbps Bluetooth 4.2 BR/EDR and LE Expansion – 2x 13 through holes and castellated holes with GPIOs, I2C, SPI, 2x UART, EN, LINK, 5V, 3.3V, and GND signals Power Supply – 3.3V or 5.5V via headers, minimum 500 mA; typical operating current: 80 […]

Allwinner A133 tablet processor pairs with XR829 or AW859A WiFi & Bluetooth chip

Last year, Allwinner published an updated roadmap for tablet processors that included A100, A200, and A300 SoC’s. None of those have been launched yet, but I’ve just noticed the Allwinner A133 quad-core Cortex-A53 processor showed up on the company’s website. That’s yet another entry-level processor coupled with a PowerVR GE8300 GPU, but you’d get support for Android 10, instead of the older Android 7.1/8.1 SDK provided for the earlier Allwinner A-series tablet processors. This time around, the company also pairs A133 processor with its own wireless chips, either XR829 WiFI 4 and Bluetooth 4.2 chip, or AW859A dual-band 802.11ac WiFi 5 and Bluetooth 5 chip. Allwinner A133 specifications: CPU – Quad-core Arm Cortex-A53 @ 1.6GHz with 32KB L1 I-cache + 32KB L1 D-cache per core, 512KB L2 cache, and CoolFlex power management architecture GPU – Imagination PowerVR GE8300 with support for OpenGL ES3.2, Vulkan 1.1, OpenCL 1.2 Memory I/F – […]

The quest for a blob-free WiFi & Bluetooth stack for BL602 WiSoC

I thought I was done writing about Bouffalo Lab BL602 WiFI & Bluetooth RISC-V SoC for a while after first covering the chip itself, and then an inexpensive BL602 development board this weekend. But the BL602 SDK has shown up in various Github repositories, including Bouffalo Lab’s own bl_iot_sdk repository, and as more people are looking into it, there’s now an effort to develop a fully open-source blob-free WiFi & Bluetooth stack for BL602, and other Bouffalo Lab WiFi and/or Bluetooth wireless chips. Last day we communicate with Bouffalolab, finally they release the SDK of BL602 (RV32 chip of wifi+bt), all code is open, except libblecontroller.a, libatcmd.a, libbl602_wifi.a (while they have all symbol inside)https://t.co/giHsQ4ezXxwe have a fork too https://t.co/FiaAIxLBc8 — Sipeed (@SipeedIO) October 27, 2020 First, Sipeed says the code is mostly open-source except for three libraries: ibblecontroller.a, libatcmd.a, libbl602_wifi.a, all of which are un-obfuscated, and easy to disassemble. Then […]

BL602 IoT SDK and $5 DT-BL10 WiFi & BLE RISC-V development board

Yesterday, we wrote about Bouffalo BL602 32-bit RISC-V WiFI and Bluetooth LE wireless SoC that should eventually compete with ESP8266 in terms of price but with more features, higher performance. and more resources like memory and storage. At the time, I noted I could not find any tools for the processor, but I was informed a BL602 SDK (Doiting_BL) and documentation had already been released on Github. The basic readme and a user manual are already available in English, but the main documentation is still in Chinese with various examples to configure GPIO, YART, WiFi, and Bluetooth. You’ll find the documentation in Github, as I could not find a website yet:

git clone https://github.com/SmartArduino/Doiting_BL

1	git clone https://github.com/SmartArduino/Doiting_BL

Go to Doiting_BL/docs/html folder and then open index.html in your browser to access the documentation. The SDK works both in Windows and Linux and relies on either Eclipse & OpenOCD or Freedom Studio & OpenOCD. A graphical software […]
