Important Notice

WARNING: HIGHLY EXPERIMENTAL DEVICE UNDER ACTIVE DEVELOPMENT. NOT A PROFESSIONAL END PRODUCT.

RakSenger is designed for RAK19001 Base Boards which have all GPIO on two 2x10meshpin headers.

   BARE PCB ONLY FOR DIY ASSEMBLY, NO COMPONENTS INCLUDED.

What you receive.

main board without components
keyboard cover with hole for 2.42" OLED display

Features:

brain is RAK4631 core module nRF52840 + SX1262
2.42" I2C OLED display
larger side USER button
optional piezo buzzer instead WisBlock

RAK WisBlock Supported Peripherals testet which I have:

RAK18001 Buzzer Module - slot D
RAK12500 GPS sensor - slot F
RAK1901 Temperature and Humidity Sensor - slot B
RAK12002 WisBlock RTC Module - slot A

Maybe other modules also works but I have only this.

As you can see there are no active components just switches and headers.

You need for assembly:

36x 1N switch 7mm height, best is DTS63K
2x female header 2x10pin
Optional side switch as user button
I2C 2.42" OLED display

Custom Firmware is for download in datasheet

I did some power consumption measurements on a Raksenger with an nRF52840 CPU. based on RAK wireless WisBlock modules.

90mA - Display ON, GPS - ON
43mA - Display ON, GPS - OFF
64mA - Display OFF, GPS - ON
21mA - Display OFF, GPS - OFF

I think these values are unbeatable. ESP32 has 10x more power consumption, The keyboard is a software-readable matrix, it does not contain any chips and is connected directly to the RAK19001 Base Boards motherboard. It only provides the connection of the display and buttons with IO pins
