Using Bluetooth LE in Products
https://www.electronics-lab.com/advices-using-bluetooth-le-products/
Jone Teel over Makezine walked through how to use BLE (Bluetooth Low Energy ), aka Bluetooth smart, in an electronic product. BLE, unlike classic Bluetooth, it’s not designed for big data transmission or streaming audio or video. BLE comes in SoC (System on Chip) ICs which combine a RF transceiver and a microcontroller running the […]
How to Upgrade Your ESP8266 SPI Flash to 4MB
https://www.electronics-lab.com/upgrade-esp8266-spi-flash-4mb-one/
ESP8266, the well known WiFi module contains an ESP8266EX SoC IC and an external SPI flash. This external SPI flash is used together with ESP8266EX to store user programs. The supported size of flash by ESP8266EX is up to 16MB but some of ESP8266 modules contain flash chips with low storage capacity like 512KB. In […]
