When we first heard about it a few weeks ago, we knew the ESP8266 UART to WiFi module was a special beast. It was cheap, gave every microcontroller the ability to connect to a WiFi network, and could ...
Few devices have hit the hacker/maker word with quite as large a bang as the ESP8266. [Brian] first reported a new $5 WiFi module back in August. Since then there have been an explosion of awesome ...
「電池 → 5V に昇圧して複数のマイコンに電源を供給したい」 という状況がよくあります。 そこで人気なのが MT3608 DC-DC 昇圧モジュール。 Aliexpress などで激安で売られている、小さな青い基板です。 しかし、このモジュールに ESP8266 を 5 個並列接続した ...
Abstract: Security of IoT micro-controllers is a crucial topic, due to the reduced capabilities that characterize such devices. In this paper, we analyze the ESP8266 module to identify its weaknesses, ...
使わなくなったスマホを常時点灯しっぱなしでディスプレイとして、使用することを考えています。 給電のため、USBケーブルを差しっぱなしにすると、スマホのバッテリーが常に満充電となってしまいます。 満充電のままだと、バッテリーの劣化がし ...
RTC or Real Time Clock is the most commonly used module in Electronics and embedded devices to keep track of time. But the problem with RTC is that the microchips in computers are not that much ...
Aiming at the current situation of traditional artificial stagnation mode (high cost, small monitoring amount and slow update of monitoring data) in the field of environmental monitoring in most areas ...
