Tiny, high-precision GPS modules target UAV’s, wearables (Sponsored)

tiny high-precision GPS modules

With the rapid development of the Internet of Things, positioning requirements are getting more strict notably with the need for higher precision and smaller GNSS modules. If you are looking for compact GPS modules that support a variety of satellite navigation systems, including China’s Beidou satellite navigation system BDS, the United States’ GPS, and Russia’s GLONASS with low power consumption (3.3V, 30mA), you may consider Ai-Thinker’s GP-01 and GP-02 GPS modules offering the smallest size. The GP-01 module has a total of 24 interfaces with five GPIO pins, while the GP-02 module has a total of 18 interfaces with three GPIO pins. These two modules are also available in development boards for ease of evaluation and development. Both are cheap, reliable, and based on the state of the art technologies. Thanks to its small size of only 10.3 x 9.9 x 2.4 mm, the GP-02 module can be easily embedded […]

Meet ESP-C3-M1 and ESP-C3-M1-I ultra small ESP32-C3 mini modules (Sponsored)

ESP-C3 mini

Half-year ago, Ai-Thinker launched new ESP32-C3 series modules that are fully pin-to-pin compatible with ESP8266, namely ESP-C3-12F, ESP-C3-32S, ESP-C3-01M, ESP-C3-13, ESP-C3-13U. After several months, the company got further requirements about the modules, notably in terms of size. So based on the demand, Ai-Thinker has now added the ESP-C3 mini series family starting with two modules: ESP32-C3-M1 and ESP-C3-M1-I measuring 16.6×13.2mm and 12.5×13.2mm respectively. The ESP-C3 mini series modules are equipped with the Espressif Systems ESP32-C3 32-bit RISC-V MCU featuring 2.4 GHz Wi-Fi & Bluetooth LE 5 connectivity, as well as a wealth of peripherals including UART, I2C, I2S, infrared, PWM, general DMA controller, USB serial port/JTAG controller, temperature sensor and so on. Some of the wonderful features of the new ESP-C3 mini modules include: ESP32-C3 MCU – 32-bit RISC-V single-core processor up to 160 MHz, with 400 KB SRAM, 384 KB ROM, 8KB RTC SRAM Storage – 4MB SPI flash […]

ESP8266 modules are still selling by the millions (Sponsored)

ESP8266 50 million units sold

The ESP8266 Series WiFi modules were designed by Ai-Thinker in 2014. Since its launch, it has been widely welcomed by customers around the world due to its high cost-effectiveness and powerful performance. Even with the launch of the ESP32 a few years ago, the demand for ESP8266 has not abated, with so far, the sales volume in 2021 exceeding 30 million units with the ESP-01S/ ESP-07/ESP-12F/ESP-12S being the most popular ESP8266 modules. ESP8266 supports the standard IEEE802.11 b/g/n protocol with a complete TCP/IP protocol stack. Users can use this module to add networking functions to existing equipment or build an independent network controller.

Designing a 3D Printed Jig to Flash Firmware to ESP8266 based Light Bulbs

Karl here. I have to say that my favorite part of 3D printing is designing things from scratch. Recently a reader was asking about a way to flash a lot of Ai Lights on a project he was working on. I suggested 3D printing a jig that pressure fits pins. He didn’t have a printer, and we exchanged contact information and he sent me one of the lights and some pogo pins from Amazon. Design in Fusion 360 I started by taking a picture of the light to get my pin placement. I set a scale by measuring a known distance then printed and tested. It took about 3 iterations to get them to line up in real life. Keep in mind camera lenses distort reality and knew It would take a couple times. I would just let a few layers print then stop and line everything up. I had […]

$12 AI Light ESP8266 based WiFi RGB Light Bulb Supports MQTT via ESPurna Open Source Firmware

AI-Thinker is famous in the maker world for their ESP8266 modules, but they’ve also recently launched a WiFi RGB light bulb that sells for about $12.5 and up on eBay and Aliexpress. Some people noticed, and bought samples online, including Xose Pérez (aka Tinkerman), ESPurna open-source firmware developer, who could confirm ESP8266 was used in the light bulb, did some investigations, and eventually added the light bulb into ESPurna, which means it can be managed using MQTT or a web interface. AI Light looks very similar to Philips Hue, but comes with WiFi instead of Zigbee. AI Light “M1636” key features: RGBW LED E27 bulb with 16.7M colors Connectivity – 802.11 b/g/n WiFi Encryption – AES Voltage Range – 110-240V LED Power – 5 watts WiFi Power Consumption – ≤0.3W Temperature Range – -5~45degree Humidity – ≤80% Certifications – FCC, CE, ROHS If you’re going to use the stock firmware, […]
