$50 Fish32 Seed “Education” ESP32 Board Comes with Plenty of I/Os, Sensors, and Connectivity Options

ESP32 Fish32 Seed Board

Sometimes I feel the word “Education” is sometimes thrown around for marketing purpose, and AnalogLamb Fish32 Seed board for “ESP32 Community Education Board” feels that way to me as so far, I could not see any tutorials or other teaching/ learning resources for the board. Having said that I can see why it could be potentially used for education: the sheer number of features, sensors, and connectivity options should allow students to learn to program my different components around ESP32. It’s just at this stage it may not be such an easy platform to learn on. Fish32 Seed board specifications: Supported ESP32 Modules – ESP32-WROVER, ALB32-WROVER, ESP32-WROOM-32 Connectivity 802.11 b/g/n WiFi and Bluetooth 4.2 via ESP32 10/100M Ethernet (RJ45) via WIZnet W5500 chip with support for up to 8 independent sockets LoRa via SX1278 chip (433 MHz) Sensors NXP MPU-9250 with 3-axis MEMS gyroscope, 3-axis MEMS accelerometer, 3-axis MEMS magnetometer Broadcom APDS-9960 digital proximity sensor, ambient light sensor, RGB color …

NanoPC-T4 Review with Android 7.1 Firmware

NanoPC T4 Connected

NanoPC-T4 is one of the many Rockchip RK3399 SBCs now available, and as we’ve seen in the “unboxing review” the company sent me two samples. So far, I’ve been reviewing RK3399 boards with Linux distributions in posts such as “Checking Out Debian and Linux SDK for VideoStrong VS-RD-RK3399 Board” and more recently “AIO-3399J Development Board Review with Ubuntu 16.04“. But in this NanoPC-T4 review, I’ll switch to Android, specifically Android 7.1, as I’ll soon try Android 8.1 on Firefly-RK3399 which might make for an interesting comparison between the two versions of the OS, before switching to Linux with Pine64 RockPro64 board which I received yesterday. First Boot with NanoPC-T4 Development Board I had already assembled  the board in the first part of the review, so I just added the two WiFi antennas, the optional USB to serial debug board, and connected various accessories and cables from left to right: USB keyboard and mouse, HDMI cable to 4K TV,  USB 3.0 …

WiFiBoy32 is an ESP32 Portable Game Console and IoT Devkit

WiFiBoy32

I’ve noticed that ever since Hardkernel launched their ODROID-GO “10th anniversary” portable game console based on ESP32 processor, most of the talk on IRC and social media is about this new toy, and people almost seem to have forgotten about the company’s Arm Linux boards 🙂 But recently, I’ve come across a somewhat similar ESP32 device called WiFiBoy32 that acts as both a portable game console and an IoT development kit. WiFIBoy32 specifications: Wireless module – ESP32-WROOM-32 wireless module with 802.11 b/g/n WiFi and Bluetooth 4.2 LE connectivity Display – 2.4″ 240×320 color SPI TFT LCD display Expansion – 2x 8-pin through holes with GPIOs, SPI, DAC, I2S,ADC, VP/VN, and power signals (3.3V, Vin, GND) Misc Top – 6x large gaming buttons, select and start push buttons, buzzer Bottom – PROG and RESET buttons, user LED USB – 1x micro USB port for power and programming (CP2102) Dimensions – 120 x 73 mm The board can be programmed with the …

Wavlink AC600 Waterproof WiFi Repeater & Router Claims up to 2 km Range

Wavlink AC600 Waterproof WiFi Repeater

WiFi is used indoors in most cases, but if you are a service provider, or own property with a park or beach, you may want to extend your WiFi coverage outdoors. The only problem is that more routers are not designed to be placed outdoors, and it’s not always easy to protect them from raining, humidity or even sunlight. So ideally in those case, you’d want a weatherproof / waterproof WiFi repeater or touter, and one of those is Wavlink AC600 dual band AC repeater / router which I first found on Banggood for $69.99.Wavlink WL-WN570HA1 AC600 router specifications: Connectivity WiFI Dual band 802.11 a/b/g/n/ac WiFi up to ~600 Mbps:  150Mbps @ 2.4 GHz, 433Mbps @ 5 Ghz Encryption mode – WPA-PSK/WPA2-PSK Transmission distance – 2km Max Functions – WDS & WPS (No VPN) “Up to 1000 mW of power and enhanced receiver design” Ethernet – Waterproof 10/100Mbps Ethernet port (RJ45) Misc – 3x LEDs for signal strength indication Power Supply – PoE via Ethernet connector Safety – Built-in lightning protection (15kV ESD). …

Want Long WiFi Range? This $10 Directional Antenna Should Help

A typical WiFi router range is limited to around 50 meters, and even less in a building with walls and competing WiFi routers. But it’s also possible to use WiFi for longer range communication, and for example, CNLohr managed to get an ESP8266 module answering ping requests over 4km away with a powerful antenna that is supposed to allow for up to 20km range and costs around $80 (NB-2G18 model). But if you’re budget is more limited, Banggood has started to sell a “10dB directional antenna” for $9.84 shipped. It is said to be for TTGO ESP32 board, but I don’t see why if would not work with other WIFI boards with a u.FL or SMA connector. Specifications listed for the antenna: Frequency – 2400~2500MHz S.W.R.: <=1.5 Antenna Gain – 10dbi Radiation – Directional antenna Polarization – Linear Impedance – 50 Ohm Wire distance – 1m Connector: IPEX The main cable features an SMA connector, but if the photos are to be believed a …

Build an ESP8266 IR Remote Control with LOLIN IR Controller Shield for D1 Mini Board

LOLIN IR Controller

Infrared remote control are still widely with TVs, set-top boxes, air conditioners, and all other sort of appliances with the end result of having many remote control around the house. If you want to cut on the number of remote controls, there are several solutions: Get a smartphone with a Built-in IR transmitter like Xiaomi Mi A1. Add an IR transmitter to your smartphones’s headphone jack using ZazaRemote or USB type C port with ROCK USB type C IR transmitter. Get a WiFi IR blaster in order to control devices remotely, or maybe buy several try control any IR devices from anywhere DIY your own solution for more flexibility, for example using ANAVI Infrared pHAT and a Raspberry Pi board. The smartphone solutions (1 & 2) works as long as you are in the room, but the WiFI IR blaster allows you to control devices even if you are not present, or even schedule times to turn the device on …

KidBright32 Board is Thailand’s BBC Micro:Bit Equivalent

BBC Micro:Bit board was first announced in July 2015. Designed for STEM education, the board was then offered to UK schools in March 2016, and a few months later UK store would start selling it worldwide. It’s now available pretty much anywhere, and you can likely find it in a local store or online. The Thai government must have seen this, and thought to themselves “If the British can do it, we can do it too!”, as the National Electronics and Computer Technology Center (NECTEC) part of Thailand’s Ministry of Science and Technology designed KidBright32 board and courses to teach STEM to Thai students. The board is based on Espressif Systems ESP32-WROOM-32 WiFI and Bluetooth module, and comes with large holes for power (5V/GND) and 6 digital inputs/outputs,  smaller through holes for I2C and more I/Os, as well as an I2C header. We’ll also find some LEDs, two dot matrix LED displays, three buttons, a buzzer, an RTC, a light …
