The only available radio chip for LoRa on the market has been the SX1272/76 from Semtech up to now. Things have changed and company IMST came up with the new type of radio chip SX1280 which can work on 2.4GHz band and decided to use this chip for their new LoRaWAN Long Range module, the […]

Sinovoip had announced its new board Banana Pi M2 Magic. At first, it is an ARM SoC development board that features a high computing performance in a 51mm square portable design. In addition to onboard WiFi and Bluetooth, M2 Magic offers 8GB eMMc storage and DDR3 SDRAM of 512 MB. There is also an SD card slot for […]

I love the Atmel AVR microcontrollers! Since building the Ghetto Development System described in this Instructable, I’ve had no end of fun experimenting with the AVR ATtiny2313 and the ATmega168 in particular. I even went so far as to write an Instructable on using switches as inputs, and extended the Ghetto Development System concept to CPLDs. During a […]

Ever since its foundation in 2007, Forlinx Embedded Tech. Co., Ltd. has been a major manufacturer and distributor of ARM technology-based embedded products such as Single Board Computers (SBCs), development boards, and many more to major companies all over the world such as Samsung, TI, Freescale, etc. Some of their SBCs are TI (Texas Instruments) […]

72 channels Serial (SPI) to parallel driver board has been designed for various applications. This project can be used as multi Solenoid driver, large size 7 segment display driver, bar graph driver, and LED driver. The project works with 5V logic levels. Output load supply 12V-48V DC and each output can drive 500mA load. I […]

With the rapid growth of technology, smartphones and e-payments are replacing cards, cash, and wallets. However, developers are still trying to keep wallets relevant in the 21st century, and Volterman is the newest attempts. Besides WiFi hotspot and power bank, Volterman also provides novel security features to protect your phone and wallet from loss. Similar to other […]

PIC microcontrollers are a very useful and versatile tool for use in many electronic projects. They are very inexpensive and easy to find. They are also very powerful and many are capable of speeds up to 64 MIPS using the internal oscillator block, about 16 times faster than most comparable AVR microcontrollers. PICs are also […]

I have used E-Ink displays in projects three years ago, but from that time the technology has greatly evolved. That time displays were hard to get, expensive and difficult to use. Now things seem to change with e-ink displays available to the maker market :-). I’m able to get a 128×296 pixel e-paper display for […]

HeartyPatch is a completely open source, single-lead, ECG-HR wearable patch with HRV (Heart Rate Variability) analysis. It is based on the popular ESP32 system-on-a-chip. By using low-cost, highly-integrated components, we are able to keep the BOM’s cost low, while the simplicity of the circuit design means future expansion will be easier. HeartyPatch can be used […]

This guide hopefully will show you how to write C code that will allow you to read in an analog input (AI) value to your PIC microcontroller. I am using a PICkit 3 programmer with a PICkit 2 18-pin demo board. The microcontroller is a PIC1827, but the ideas discussed in this article will be […]
