Beelink Mini S

I wasn’t satisfied by Pico PC so,

I bought another mini PC. the Beelink Mini S

Here are some specs.

Better than Pico PC

Silent : most important Pico PC doesn’t include PWM controlled FAN. (what I mostly disappointed about Pico PC)
Slightly faster. N95 is slightly faster than J series

Weaknesses?

When I was using raspberry pi, I bought a IR transceiver module for Arduino. and used it for several years. IR transceiver

Raspberyr Pi, IR Transceiver and DHT11

And this year, I am interested in ESP8266, so I bought another IR receiver, IR transmitter.

Install esp8266 and voltage converter on breadboard.
