You should add components slowly to the ESP8266 (one additional circuit at a time) so you know where to look should the ESP8266 suddenly stop working. So, if your ESP8266 does not boot after adding, say an active high push-button circuit, try switching things around and make it an active low push-button circuit (or vice versa). These pull-up resistors cause some devices like push buttons not to work as expected.

On the HC series chips you can lower the Vcc supply voltage to 3.3V and not have to worry about voltage level shifting.Ĥ.) Some of the ESP8266 GPIO pin either have external pull-up or pull-down resistors which are used on power-up boot (or reset) time to tell the chip how to boot, etc. Another trick is to use 74HCxxx series TTL componets where “HC” means high speed CMOS.

I always use 2 resistor voltage dividers or voltage level shifter modules. but most folks when cornered about the topic will recommend using them (“better safe than sorry”). The documentation says the inputs are rated to handle up to 5.8V, and some peole get by without these level shifters, etc. There are a few ways to do this.Ģ.) There is only one ADC on the ESP8266,ģ.) The board, like the Arduino Due is a 3.3V system, so things like voltage divider resistors, bidirectional level circuits (or modules) usually based on FETs, and other tricks are required to match voltage levels, especially the 5V outputs of TTL chips leading to the 3.3V inputs of the ESP8266. The only stumbling points are:ġ.) The NODEMCU “Arduino friendly” pin names (D0 thru D8, plus RX and TX) don’t correspond with the actual ESP8266 GPIO pin numbers, so you have to make special arrangements to map the “D1”, “D2”, etc names to the actual GPIO pin numbers.

It uses a somewhat different tool chain to compile the Arduino C code into binary files executable by the ESP8266, but the Arduino IDE and most libraries are the same. Both of these boards also use a WCH CH340G USB-to-UART bridge chip.Īs an Arduino-phil I use the ESP8266 Core from GitHub to adapt the Arduino IDE to the ESP8266.

I suspect the same will be true for the Amica v0.9 (yellow or blue PCB) NodeMCUs (both considered out-dated) and the DoIt/SmartArduino brand NodeMCU V2.

I have also found that these drivers work fine when connecting the LoLin NodeMCU V3 to my Windows 7 PC (I had to do nothing, since I had already loaded the drivers for my cheap Chinese Arduino Nano clones).
