Recently there are some discussion regarding whether ESP8266 I/Os are 5V tolerant. The most active one being the article on Hackaday. The same article was shared on ESP8266 Facebook group and Espressif CEO Mr Teo Swee Ann commented that “i can reply officially here: it is 5V tolerant at the IO. while the supply voltage is at 3.3V.”
In the recent Maker Faire I demonstrated an ESP8266 MQTT VFD clock. Some readers had wrote to ask for the soure code. Because the project was builtup within only 2 days, the actual source code is more or less of spaghette type. However the underlying MQTT client may be useful to someone who likes the RTOS SDK.
Well I’ve been bit lapse. This post is supposed to written in July.
Another year, another Maker Faire. Yes! for this year it is nolonger “Mini Maker Faire”, we’ve just upgraded to the full fledged “Maker Faire” event. As Singapore Maker Faire has grown 10 times compare to 3 year ago, I am not able to cover every single booth or exhibit in the event. I only write about those I’m interested in. Continue reading
The rise of the ESP8266 WiFi chip was almost overnight with Espressif’s open approach and pushing from Hackaday. While no ground-breaking product has yet emerged, the development on the chip are phenomenon. However due to an unknown reason the ESP8266 modules manufacture seems to prefer non-standard 2.0mm pitch connector, which gives a lot of headache to breadboarding lovers like me. This forced me to make a breadboard friendly ESP8266 breakout board.
Happy New Year!
