ESP-01 in 2020 - outdated or still just as good?
Is the ESP-01 and ESP-01S from the ESP8266 family still relevant in 2020?
Is it still worth buying?
The ESP01 was the first in the ESP8266 family that became very popular. But this was a while back. Now you can get these small modules for under $2. But are they still any good, or are they outdated?
