News
Within the LoRa-E5 mini board and the Arduino UNO shaped LoRa-E5, Seeed Studio included the LoRa-E5 STM32WL module.
The two kits support LoRaWAN protocol and boast a transmission range up to 10km and ultra-low power consumption.
Features of the LoRa-E5 mini board according to the company include the following:
-
LoRa connectivity
-
LoRa-E5 modules based on STM32WLE5JC SoC with Arm Cortex-M4 MCU @ 48 MHz with 256 KB flash memory, 64 KB SRAM, SX126x LoRa radio
-
Modulations – LoRa, (G)FSK, (G)MSK, BPSK
-
Operating frequencies – 868/915MHz (EU868, US915, AU915, AS923, KR920, IN865)
-
Output power – up to +20.8 dBm at 3.3V
-
Rx sensitivity – -116.5 dBm to -136 dBm
-
SMA-K and IPEX antenna connectors
-
USB – 1x USB Type-C port for power and programming
-
LoRa-E5 mini – 2x 12-pin through-hole and castellated headers with GPIO, UART, ADC, SPI, I2C.
Features of the Arduino UNO shaped LoRa-E5 according to the company include the following:
-
Arduino headers (but not fully compatible with Arduino shields)
-
3x Grove headers (2x I2C, 1x UART)
-
3-pin RS485 terminal block
-
5x 4-pin headers for SPI, USART, I2C, USB to TTL, LPUART
-
User button, configuration jumpers, SWIM/SWD debug header
-
Supply voltage – 5V via USB-C port or ~3.7V battery via 2-pin header (LoRa-E5 mini) or 2-pin JST connector (LoRa-E5 devboard)
-
Sleep current as low as 2.1uA (WOR mode)
In addition to the boards themselves, users also receive an antenna 868 MHz or 915 MHz, a 20cm USB Type-C cable, and a battery holder for two AA batteries. Further, they are able to be controlled with the use of AT commands sent over USB to a PC or over UART from another board.
