LoRa32u4 II Lora Module Development Board LiPo Atmega328 SX1276 HPD13 868MHZ 915Mhz with Antenna for Arduino IOT Internet of Things Lorawan
Description:
LoRa32u4 II is a light and low consumption board based on the Atmega32u4 and HPD13 868MHZ LoRA module 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 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.
HPD13 wireless module, using high-performance, highly integrated RF transceiver chip SX1276 design. Advanced LoRaTM spread spectrum communication technology to ensure that the module communication distance and anti-jamming capability greatly improved, and also achieved a very low current consumption. In the LoRaTM mode, the HPD13 provides higher reception sensitivity performance, more robust anti-jamming capability, and improved communication distance and reliability compared to the same transmit and receive modules on the market. In normal (G) FSK mode, it also provides industry-specific receiver sensitivity, as well as very high communication rates.

Everything works, everything is fine.
Got fast. Not yet checked but I order not the first time. These boards for developing the thing is excellent.
a good product
Super quick shipment. Everything as expected! Thanks!
genial
Works perfectly !
TOP !!
Haven't had yet a time to test the product, but the initial impression is for good manufacturing quality. A postcard with link to online documentation and code samples of this and many other products of store's list was included. Recommended seller!
Good store. Item as described.
Qualitatively assembled. Quickly delivered.
As described and working great.
The concept scheme differs significantly from version 1.2, a bunch of unbreakable elements, where to take the scheme is unclear, the search did not find. The store simply did not reply to the request of the scheme. There was no COM port in Arduino until the bootloader was re-asked. In general, some problems with this version, it would be better to have an old one.
Excelent product, I'm very happy.
thanks for fast delivery
not tested yet
32u4 is really hard to work with. Need right driver but works ok
Good service, quick delivery. Regarding products, these cards are not good for developing purposes, since the serial port is the same for bootloader and for application, is not easy to flash the cards, you need to constantly double push the reset button
Quality item. Quick Shipping.
looking good
Spectacular
Very fast shipping
Item arrived in Ireland in 20 days from order date, and is as described.
looks in good shape
They work well. Change in ide lmic pin 6 for 5 example.
Arrived in good condition. Still need to test
Looks like it works though eye is v1.3 not v1.2
Good product
perfect
So fare the blink is working, but I do not know, is it a 868MHz or 915MHz Module.
thanks, fast delivery
great service
ok
Thanks Friend A+++
Received in less than two weeks. Shipped same day. I'm very satisfied! About device. It's a some kind a copy of the Adafruit Feather 32u4 LoRa. Board is labeled as v1.2 and need little modification to work with limc software. At first time when i try to remove antenna, male U.FL connector disconnects from soldering pads, but it was easy to solder it back
Yakutsk reached in 50 days. Track tracked.
The product works well. I did some tests in an urban environment with a very poor line of sight and consistently achieved at least 1km of range. I haven't tested it in a location with good line of sight as of yet. I am satisfied with my purchase.
All OK. I'm very satisfied
