This is a SAMR34 based LoRa dev-board with all the necessary components for fast prototyping. It’s a successor of my previous Penguino RF module and Feather breakout design ( https://www.tindie.com/products/16985/ )The new design uses the RAK4260 module from @RAKWireless and improves on some aspects, such as USB Type-C, RGB LED, user button, battery protection & voltage supervision, and optional flash & per-provisioned secure element IC pads.
Lousey was designed to provide to PICmicro the ability to stick to FeatherWings and use many of the boards from its ecosystem.
Lousey uses a PIC18F2550 that provides USB connectivity along with a bootloader. Alternatively it can be used within the Pinguino IDE .
The pins were laid out in order to provide analog inputs/outputs (PWM) and interrupts on the same pins as the original Feathers. The same applies for communication features but that require the configuration of solder jumpers because the PIC Micro shares the same pins silicon (and hence the same pins) to provide I2C, SPI and RS232. Eventually, it might be necessary to use more than one communication interface and that can be accomplished by using hardware for the most critical interface and software for the others.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
