STM32WLEx product page; note that this MCU has an integrated Semtech SX1262.
Meshtastic firmware support is still WIP (booting and functional, but no writeable configuration storage); see [Board]: STM32WL (Seeed Studio Wio-E5) #2539
Note: Meshtastic only supports modules with SPI connectivity; UART modules are not supported.
Note: Transmit power of SX1262 must be configured per the table below to achieve the desired transmit power (data provided by EBYTE by email):
SX1262 Tx Power (dBm) | Actual Tx Power at 868 MHz (dBm) | VIN Current (mA) |
---|---|---|
20 | 30.54 | 618.12 |
17 | 27.98 | 518.43 |
14 | 24.75 | 440.35 |
11 | 21.73 | 398.87 |
8 | 18.81 | 377.56 |
5 | 15.67 | 366.21 |
2 | 12.88 | 352.61 |
-1 | 9.92 | 344.76 |
Note: Transmit power of SX1262 must be configured per the table below to achieve the desired transmit power (from datasheet page 5):
SX1262 Tx Power (dBm) | Actual Tx Power at 850 MHz (dBm) |
---|---|
8 | 33.0 |
5 | 31.6 |
3 | 30.0 |
0 | 27.2 |
-3 | 23.6 |
