Penguino STM32WL MAMWLE-C1 LoRa growth board Options Transfer Options’ MAMWLE SoM

Electronics maker Orkhan Amiraslan has unveiled a brand new GPIO-Wealthy Lora-capable Penguino board primarily based on Transfer Options’ MAMWLE SoM.

The compact Penguino STM32WL MAMWLE-C1 LoRa dev board differentiates itself when it comes to energy, dimension, and suppleness. It’s geared up with STMicroelectronics’ STM32WL‘s core that purposely targets low-power operation. It additionally breaks out all obtainable GPIOs and affords the choice of selecting both the +14dBm or the +22dBm output path.

“This enables the consumer to rigorously select the max output energy and save on the battery life,” says Amiraslan. The LoRa dev board additionally has an Adafruit Feather-compatible kind issue that makes it suitable with many addons wanted to finish any resolution. “Remember to take a look at the awesome-feather repo,” he added.

The low-power feather-compatible board additionally comes with all the mandatory parts for speedy prototyping.

“This board packs the whole lot you want for LoRa/LoRaWAN Improvement. It has quite a lot of GPIO to entry sensors and peripheral management, a STM32WLE5x MCU, and a Cortex M4 CPU with sufficient energy,” says a assessment that was left by a consumer recognized as “Rony”. “You’ll nonetheless want some growth expertise for STM32 units or use their Arduino port which is able to want some changes to work on this board,” he added.

Specs of the SoC:

  • ARM Cortex-M4 core that focuses on low-power
  • Built-in SX1262 RF transceiver
  • 150 MHz to 960 MHz frequency vary.
  • LoRa®, (G)FSK, (G)MSK and BPSK Modulations
  • As much as +22 dBm transmitter energy

The MAMWLE-C1 SoM itself is a 15 x 16 millimeter board that mixes an STM32WL microprocessor and a Semtech SX1262 sub-GHz radio.

Options of the MAMWLE-C1 SoM Embody:

  • Multiprotocol LPWAN 32-Bit Arm Cortex-M4 operating at 32 MHz
  • LoRa, (G)FSK, (G)MSK and BPSK help
  • 128 kilobytes of flash reminiscence
  • 64 kilobytes of SRAM
  • ADC, DAC, DMA, comparators, timers and unbiased watchdog timer
  • Numerous ultra-low-power options
  • Frequency vary: 868Mhz ~ 915Mhz
  • As much as 37 general-purpose IOs, 2x SPI, 3x I2C, 2x USART, 1x LPUART, 1x JTAG, 1x SWDIO
  • Clock: 32MHz TCXO, 32.768KHz XTAL
  • Tx energy:
    • As much as +14dBm (low energy path)
    • As much as +22dBm (excessive energy path)
  • Dimensions: 16.5mm x 15.5mm x 2.0mm

You may need to get a male 868/915MHz SMA antenna at hand or order for one as there’s a default antenna path routed to the SMA edge connector however no antenna function on the board.

Additional particulars on the Penguino STM32WL MAMWLE-C1 may be discovered on Tindie the place it at present sells for $34.95. You can too go to GitHub for the KiCad design information, Gerbers, and an instance STM32Cube venture.
