ESP serial Wi-Fi UART wireless IOT module 3.3V AP+STA   For RasPi, arduino, AVR, other MCU ESP serial wifi Order multiple quantity or multiple items from 4d_innovations to save on shipping cost.   Product Description esp serial wifi:   ESP is a highly integrated chip designed for the needs of a new connected IoT world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. Note:   This module requires a 3.3V supply for VCC, and 3.3V logic. It is not 5V tolerant. Connecting Rx or Tx on 5V Arduino may destroy this module. You must use a logic level converter, or a 3.3V Arduino. Also the 3.3V supply on the Arduino Uno has inadequate current capability to power this module. You must provide a separate, higher 3.3V supply (about 300mA or better)   Features ESP serial wifi: ·         SDIO 2.0, SPI, UART ·         Integrated RF switch, balun, 24dBm PA, DCXO, and PMU ·         Integrated RISC processor, on-chip memory and external memory interfaces ·         Integrated MAC/baseband processors ·         Quality of Service management ·         I2S interface for high fidelity audio applications ·         On-chip low-dropout linear regulators for all internal supplies ·         Proprietary spurious-free clock generation architecture ·         Integrated WEP, TKIP, AES, and WAPI engines   Specification ESPEX: ·             b/g/n ·             Wi-Fi Direct (P2P), soft-AP ·             Integrated TCP/IP protocol stack ·             Integrated TR switch, balun, LNA, power amplifier and matching network ·             Integrated PLLs, regulators, DCXO and power management units ·             +19.5dBm output power

      The USB to RS232 converter board is most essential bridge needed to connect serial device to log the data to pc or laptop. If you have a development board like 8051, AVR, PIC or any other with serial UART or RS232 connector. Then use the USB to RS232 converter to connect these devices for programming or communication with the PC or Laptop.              Now a days most of the laptops does not have COM ports to connect directly with RS232 cable. So use i-labz USB to RS232 converter for interfacing. If you are planning to buy 8051, AVR, PIC or any other boards like GSM modem, GPS, Bluetooth, Finger print scanner or Ultrasonic distance finder then you must use USB to RS232 connector for connecting or troubleshooting with laptop. CP210x Driver Installation Guide - USB Driver Installation Instructions Download Terminal tool for Troubleshooting(winXP/7/8)               To test the USB to RS232 converter use windows hiighper terminal (using winXP as OS) or terminal tool. The procedure to test to setup the highper terminal is explained

Product Description Note Not Genuine IC will have much more error programming. This is a redesigned CP module, fully compatible with arduino pro mini, why? because all the pins are same as our FTDI basic board, and most important is the DTR pin enabled as FTDI, so you can directly upload sketch with this one. So what is the advantage? The price is almost only one third of the FTDI basic Features: Use SILABS’s CP chip, performance is definitely more than made ​​PL, encroaching FT232RL. Full board design, full-featured interface. With RXD TXD RST 3.3V 5V DTR DCD RI RTS CTS and other full-featured interface. Some boards can’t work with normal CP boards because of the incomplete interface, now it is not a problem anymore. With 500mA resettable fuse   designed to prevent users from burning power pick the wrong computer USB, this is a must. Get hold of the plate board computer motherboard burned more harm than good. With power indicator light. Directly computer USB interface design, you can not use the computer switch wiring or extension cords. Package includes five DuPont line, you can link directly target board. Convenient and flexible. Transmission speed bps easily qualified, definitely more than PL. Borrow computer USB power supply, 3.3V and 5V power output can be provided directly to the user’s target board. Note: RXD TXD Some devices mark is not standard, even if not directly, please cross-connect. Powered by Turbo Lister

Walnut GSM/GPRS Modem USB The GSM/GPRS Modem USB uses SIM900A based Quad band MHz GSM / GPRS module. It can be connected to PC or laptop via  USB directly or to a microcontroller UART using TTL levels. The modem consists of all the external circuit required to start experimenting with the SIM900A module like the power regulation, external antenna, SIM Holder, etc. Modem is built with Quad Band GSM/GPRS based SIM900A module from SIMCOM. It works on frequencies MHz. SIM900A can search these bands automatically. The frequency bands can also be set by AT Commands. The baud rate is configurable from through AT command. The GSM/GPRS Modem is having internal TCP/IP stack to enable you to connect with internet via GPRS. Best suited for GSM based Microcontroller Projects (better than SIM300 and other GSM Modems) **** Can be Use for Bulk SMS sending using Compatible software. Features: U ses the extremely popular SIM900A GSM module. Accepts commands through On board USB serial. Also can accept commands from microcontroller UART. Provides serial TTL interface for easy and direct interface to microcontrollers. Works on 9V-18V 1 A SMPS supply. Speaker and Microphone pins onboard for voice Communication. On board SMA connector with GSM antenna. On board Power, Network, Ring and status LED’s for indication. Can do basic functions which can be done via normal phone like calling, send sms, access data through GPRS etc. Plug and play device. Can accept commands through Hyper Terminal. Ft232 R  Based USB communication- Better and Faster than other Cheap USB Drivers. Supports Windows / Vista / Server / XP / SE / MaC OS X / Mac OS 9,Linux 3.x.x / 2.x.x. Small size. NOTE: The modem consumes current of nearly 1A during transmission; please make sure that your power supply can handle such currents. Modems are pretested before shipping. We recommend to use a 12V DC 2 Amps power supply & Use USB Cable to Connect GSM MODEM to PC or Laptop. Please be very gentle with the SIM card tray while inserting or removing the SIM card. Also don't tighten the screws of the antenna too much, just make sure it is connected properly without exerting too much force to tighen the antenna.
