I just got in the latest batch of PCBs for my Kilroy Development board! Feel free to download and make your own from the project page!
Originally created in 2006, the Kilroy Development Board has given thousands (~450 per year) of middle and high school students the opportunity to learn basic electronics and programming. Using PICAXE‘s 18X, and now the 20×2/20m2 microcontroller, students can now program in BASIC and take full advantage of Arduino’s wide range of shields. The latest version of Kilroy incorporates the following features:
USB programming via the FT232RL
RS232/5V Serial programming via the PICAXE 1/8″ programming cable
2 x Servo headers
Complete compatibility with Arduino pinout
The PICAXE 20×2 microcontroller has the following features:
Memory (lines): 1000
I/O Pins: 17
Outputs/Inputs: 1-17 (Configurable)
ADC (L=low): 0-8
Data Memory: 128 +i2c+128 Scratch
Based on the PIC PIC18F14K22
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
