Penguino-STM32WL-LoRa-E5

Seeedstudio's LoRa-E5 STM32WLE5JC module was recently announced, and I took the liberty of designing a Penguino Feather breakout board for it. Hopefully OSHW community would benfit from it.

About the Penguino Feather breakout

Managed to fit everything on a +2 layer (H1.6mm) low-cost PCB. Careful design choices allowed to have a good GND plane on the back to to achieve good (theoretical) RF performance.

Current version: 0.1

Board requirements are standard:

• 6mil traces/clearance
• 0.3mm drill

Specs (SoC):

• STM32WLE5JC Wireless SoC
• ARM Cortex M4 ultra-low-power MCU
• Integrated SX1262 RF transciever
• Frequency range: 150 MHz to 960 MHz.
• Modulation: LoRa®, (G)FSK, (G)MSK and BPSK
• Transmitter power: programmable up to +22 dBm

Specs (LoRa-E5 module):

• Frequency range: EU868/US915/AU915/AS923/KR920/IN865 (high-band design). FCC and CE Certified
• Ultra-low Power Consumption: as low as 2.1uA sleep current (WOR mode)
• High Performance: TXOP=22dBm@868/915MHz; -136.5dBm sensitivity for SF12 with 125KHz BW
• Long Distance Use: 158dB link budget
• Size: 12mm * 12mm * 2.5mm 28 pins SMT
• For further specs plese see the respective product pages.
