(Just used a 5K pullup resistor to 3V3, just in case but it worked without it too). I would like to know if using UART serial without any level converter should work too.
The logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side. Two inputs and two outputs are provided for each side. Can be used with normal serial, I2C, SPI, and any other digital signal.

More traditional Arduino boards such as an UNO or a Nano have a 5V logic level, which means when you set a pin HIGH, it will measure as 5V. But other common boards such the ESP8266 have a 3.3V logic level, which, as you can probably guess, means that when you set a pin HIGH it will measure as 3.3V.Schottky Diode Bi-Directional Logic Level Conversion. When connecting 3.3V devices and 5V devices voltage level conversion is required. The following circuit will allow this to be done bi-directionally using only a schottky diode and resistor. A schottky diode is used because it's forward voltage drop is less than a normal diode (~ 0.3V) Note: The ESP8266 Module is not capable of 5-3V logic shifting and will require an external Logic Level Converter. Please do not power it directly from your 5V dev board. Exitlag crack accountBecause the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V. We do have some other handy level shifters in the shop, from the DIP 74LVC245 to the fancy bi-directional TXB0108.

Jul 27, 2018 · Now this is a 5V device and since the ESP8266 is strictly a 3.3V device, we should really use a logic level converter, but at a pinch it should work at 3.3V, especially if I powered it from the ESP-12E. I also used a modified version of the Trialcommand ESP8255 Master Modbus RTU (RS232) sketch.
Pueblo county sheriff arrests pdfThe Adafruit I2C-safe Logic Level Converter lets your 5V Arduino (or other microcontroller) talk to 3.3V sensors, displays and flash cards over I2C. Ordinary level shifters won't work with I2C but this bi-directional shifter from Adafruit is specifically designed to do just that. This J1Y transistor is a BSS138 whose purpose is to enable 5V logic level circuits to communicate with 3.3V logic level circuits and vice versa. Since the ESP8266 has a logic level of 3.3V and the Arduino has a logical level of 5V, it is necessary to use a logic level converter to ensure the perfect operation of the ESP8266.si votre interface n'est pas en 3.3v ( alimentation et signal ) mais en 5v munissez vous d'une interface " Logic Level Converter Bi-Directional Module 5V to 3.3V " ( ou d'un montage à base de pont diviseur ou autre faire des recherches sur le net ) car l'esp8266 fonctionne en 3v3 et ne supporte pas le 5v.
