The TTGO T-Beam offers 26-pin headers with GPIO, ADC, VP/VN, DAC, touch, SPI, I2C, UART, 2דLoRa” pin, and power signals (5V/3.3V/GND) There are also two buttons on the board—one is for power, but the second is connected to the GPIO39 pin of the ESP32.

Pin Description:

The board is built around a dual-core ESP32 chip, with 4MB of SPI flash onboard, providing both Wi-Fi and Bluetooth LE via a “3D antenna” on the PCB. The board’s LoRa support comes in three different variants, operating at 433MHz, 868MHz, and 915MHz depending on region, with an included SMA antenna. While location tracking is provided by the onboard u-Blox NEO-6M GPS module with a ceramic antenna.

The board can be programmed using the Arduino development environment, and the example code shows you how to both send and receive data via LoRa.Flipping the board over there is a battery holder for a 18650 Li-Ion cell, and while a 18650 sort of looks like a “standard” AA battery, it’s significantly different. So don’t make the mistake of substituting in the more common AA battery to try and power the board. They’re not quite the same size, but I’ve seen people attempt this substitution nonetheless.

Features:

1. Highly configurable data packet processing program, the configuration parameter data can be saved in EEPROM.
2. ERP32 with the new version REV1 supports wireless Internet access and wireless Bluetooth connection.
3. Designated module with ceramic antenna and super signal, supports automatic gain control and automatic frequency correction.
4. GPS With the help of a global positioning system, GPS module NEO-6M, 3V-5V universal power supply.
5. It also has a digital RSSI function, RF wake-up function,
6. 4MB flash memory,
7. Low voltage detection, and temperature sensor,
8. Fast wake-up and frequency hopping LED signal indicator, and battery with data backup.

Lora Shield is a long-range transceiver on an Arduino shield form factor and based on an Open source library. The Lora Shield allows the user to send data and reach extremely long ranges at low data rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
The Lora Shield based on RFM95W/RFM98W targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.
Using Hope RF’s patented LoRaTM modulation technique the Lora Shield can achieve a sensitivity of over -148dBm using a low-cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.
These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The Lora Shield deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.

Features:

1. Excellent blocking immunity.
2. Low RX current of 10.3 mA, 200 nA register retention.
3. Fully integrated synthesizer with a resolution of 61 Hz.
4. FSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation.
5. Built-in bit synchronizer for clock recovery.
6. Preamble detection.
7. Automatic RF Sense and CAD with ultra-fast AFC.
8. Packet engine up to 256 bytes with CRC.
9. Built-in temperature sensor and low battery indicator.

Package Includes:

1 x Wireless Transmitter 433Mhz
