just dongle, not programmer
6 von 6 finden das hilfreich does not work to program only power and communication. pins GPIO0 and GPIO2 are tied to +3V with 10K resistors. RST pin is floating on header. No way to bring GPIO0 to ground to allow flashing. only RX/TX connected to header. works as dongle to power ESP-01 and communicate with ttl serial i/o. Does not work to flash firmware to ESP8266.

works well to burn/etch paper, wood, leather
this laser works great in my DIY etching system. The focus is sensitive, and must be set correctly for it to burn. I got two of these. In one laser I had to reverse the black optics threaded column (it arrived with optics backwards) to get it to focus correctly. very bright, and will burn. draws 0.23 amp at 5 volts. It is only 1 watt, so cutting is slow and limited, but it will cut paper eventually.

new small microphone modules
have not used yet, but they appear to be new modules in good shape. they need a driver since they are electret condenser micrphones.
