Rethinking Arduino for convenient prototyping

Pailhoux who runs the French-language Youtube channel U꞊RI about DIY electronics, has come up with many tutorial projects based on Arduino boards, and in this respect, describes himself as a fervent Arduino ambassador amongst his 20,000+ followers. But from his experience creating fun projects with Arduino boards, he encountered a number of practical issues, such as shields that completely hide the silkscreen and the reset push-button, only one pin out for each signal, female headers that can slightly hide the silkscreen. Does this sound familiar?

With a U-shaped PCB dubbed DevDuino, Pailhoux promises to add many practical prototyping features while making the board breadboard-friendly and capable of receiving mezzanine shields on its bottom side using male headers.

So far, the DevDuino KickStarter has already raised €51,235, well beyond Pailhoux’ €8,000 humble goal. 

Designed to become a day-to-day assistant in fast prototyping, sensors evaluation and debugging for any professional electronics engineer, DevDuino is built around a low-power Microchip 8-bit AVR RISC-based MCU with 32KB of self-programming flash program memory, 2.5KB of SRAM, 1KB EEPROM, USB 2.0 full-speed/low speed device, 12-channel 10-bit A/D-converter, and JTAG interface for on-chip-debug.

The chip guarantees up to 16 MIPS throughput at 16MHz, operating from 2.7 to 5.5V. Because the board features status LEDs for about just everything (28 in total), from power or reset status to analog inputs and general purpose IOs (17 of them) together with an onboard 1.3 Inches 128×64 OLED display, all signals status and digital data are readily visible, making for a more responsive platform when debugging your circuit and code. To ease wireless connectivity, the board has a single connector for interchangeable Wi-Fi and Bluetooth modules which are provided. Other features include a Micro-SD slot for data logging or memory extension, a real time clock with a CR1220 3V back-up battery slot, a temperature sensor, and a slot for a two-wire voltmeter to probe voltages running on-board.

Thanks to its breadboard-compatibility (a breadboard with 830 tie-points is included among the accessories), the DevDuino has been designed to be also a plug & play sensors evaluation platform for low cost manufacturing modules.

All this comes at 59€, with all the accessories, plus three µStripboard which were added as the campaign’s first stretch goal. As a secondary stretch goal (already reached), Pailhoux will have community website professionally developed for backers of the DevDuino, hosting all the documentation, tutorials, projects and support to be, including for future add-on modules and extension boards.
