Bonitos convertidores de nivel lógico. Tenga en cuenta que necesita alimentarlo con 5V Y 3,3 V. Tienes dos canales. Para cada uno hay una clavija de transmisión y una clavija de recepción.
I am pleased. Super little gadgets.
it is a excellent products at low price and working nice as a voltage level converter between arduino uno and esp8266-01. Packing of the product was good.
Works well. Easy to use.
Ordinati il 23 marzo ho scelto la spedizione con Priority Direct Mail; sono arrivati l'11 aprile. Come da descrizione. Imballo perfetto. Non l'ho ancora testato.
The inputs / outputs of the Arduino DUE can accept 3.3V only. If you want to connect the Arduino DUE to TTL technology circuits (5V), you must have these modules. WARNING: THE MODULE CAME WITH NON-WELDED PINS.
The RX pins are unidirectional high to low. The TX pins are bidirectional high to low or low to high. This makes the board ideal for a variety of uses. See http://cdn.sparkfun.com/datasheets/BreakoutBoards/Logic_Level_Converter.pdf for svhematic diagram of the board.
Good for a lot of application, see https://learn.sparkfun.com/tutorials/using-the-logic-level-converter for complete infos.
I used this level converter to control the 5v relay module with 3.3v wifi shield.. Works like a charm! http://www.banggood.com/ESP8266-ESP-03-Remote-Serial-Port-WIFI-Transceiver-Wireless-Module-p-961244.html http://www.banggood.com/5Pcs-5V-1-Channel-HL-Trigger-Optocoupler-Relay-Module-For-Arduino-p-945176.html
