Check the listing for details. LoRa32u4 433MHz Development Board RA02 LoRa Module I2C SPI w/Antenna for Arduino. Condition: New. Listed at 17.99 USD. Description: LoRa32u4 is a light and low consumption board based on the Atmega32u4 and 433MHz LoRA module RA02 from AI-Thinker and an USB battery charging circuit. Ideal for creating long range wireless networks that can exceed 2.4 GHz 802.15.4 and similar, it is more flexible than Bluetooth LE, does not require high power unlike WiFi and offers long range. Packet radio with ready-to-go Arduino libraries License-free ISM bands (ITU "Europe" @ 433MHz) +5 to +20 dBm up to 100 mW Power Output Capability (selectable in software) ~300uA during full sleep ~120mA peak during +20dBm transmit ~40mA during active radio listening. U.FL (IP) antenna connector Package included: 1 X LoRa32U4 module 1 X 433MHz 470MHz FPC Antenna 1.13 IPEX Interface LoRa32u4 433MHz Development Board RA02 LoRa Module I2C SPI w/Antenna for ArduinoLoRa32U4 module Antenna Description: 433M 470MHz FPC Antenna 1.13 IPEX Interface for Lora RA-02 Module Description: LoRa32u4 is a light and low consumption board based on the Atmega32u4 and 433MHz LoRA module RA02 from AI-Thinker and an USB battery charging circuit. Ideal for creating long range wireless networks that can exceed 2.4 GHz 802.15.4 and similar, it is more flexible than Bluetooth LE, does not require high power unlike WiFi and offers long range. The RA02 LoRa module is fitted with an U.FL (IPX) external antenna connector. The ATmega32u4 is clocked at 8 MHz and 3.3 V. This chip has 32 K of flash, 2 K of RAM and built-in USB to Serial communication, debugging and programming capabilities without the need for an external FTDI chip, it can also act as an HID device (mouse, keyboard, USB MIDI device, etc). This board is also equipped with a LiPo and Liion charging circuit and a standard battery interface. It is fully compatible with Arduino. A white user led is tied to pin 13. An orange LED is used for charging status. Feature: ATmega32u4 @ 8MHz with 3.3V logic/power 3.3V regulator with 500mA peak current output USB native support, comes with USB bootloader and serial port debugging 20 GPIOs Hardware Serial, hardware I2C, hardware SPI support Built in 100mA lipoly charger with charging status indicator LED Power/enable pin 4 mounting holes Reset button SX1278 RA02 LoRa® based module with SPI interface 8 x PWM pins 10 x analog inputs Packet radio with ready-to-go Arduino libraries License-free ISM bands (ITU "Europe" @ 433MHz) +5 to +20 dBm up to 100 mW Power Output Capability (selectable in software) ~300uA during full sleep ~120mA peak during +20dBm transmit ~40mA during active radio listening. U.FL (IP) antenna connector NOTE: In the new version of LoRa32u4 (V1.4) the battery monitoring circuit is now active to save power, that mean it has to be enabled before the battery voltage can be measured on ADC channel (9) the battery monitoring ENable is PD5, so PD5 must be set HIGH before he measure voltage with ADC (9) and then PD5 as to be set LOW again, to disable the circuit. The voltage divider bridge on battery monitoring circuit (to ADC (9), is 100K and 27K, 1% Datasheet MPC73831 http://ww1.microchip.com/downloads/en/DeviceDoc/20001984g.pdf Datasheet RA02 http://wiki.ai-thinker.com/lora Datasheet SX1278 http://www.semtech.com/images/datasheet/sx1276_77_78_79.pdfPinout diagram:http://www.diymalls.com/files/DIY0031-lora32u4.zip Package included: 1 X LoRa32U4 module1 X 433MHz 470MHz FPC Antenna 1.13 IPEX Interface PaymentShippingDelivery timeReturn PolicyContact usPaymentPlease kindly make payment asap, so that we can arrange your order promtly.
