Making an Arduino Shield PCB with Fritzing

[Allan Schwartz] decided to document his experience using Fritzing to design, fabricate, and test a custom Arduino shield PCB, and his step-by-step documentation makes the workflow very clear. Anyone who is curious or has been looking for an opportunity to get started will find [Allan]’s process useful to follow. The PCB in question has two shift registers, eight LEDs, eight buttons, and fits onto an Arduino; it’s just complex enough to demonstrate useful design features and methods while remaining accessible.

[Allan] starts with a basic breadboard design, draws a schematic, prototypes the circuit, then designs the PCB and orders it …read more

Hackaday Prize Entry: A Tiva Shaped Like an Arduino

Texas Instruments’ Tiva C LaunchPad showcases TI’s ARM Cortex-M4F, a 32-bit, 80Mhz microcontroller based on the TM4C123GH6PM. The Tiva series of LaunchPads serve as TI’s equivalent of the Arduino Uno, and hovers at about the same price point, except with more processing power and a sane geometry for the GPIO pins.

The Tiva’s processor runs five times faster than standard ATMega328P, and it sports 40 multipurpose GPIO pins and multiple serial ports. Just like the Arduino has shields, the Tiva has Booster Packs, and TI offers a decent number of options—but nothing like the Arduino’s ecosystem.

[Jacob]’s Arduino-Tiva project, an …read more
