dsPIC30F4011 DIP-40 Development Board

A through-hole, single-supply platform for mixed-signal DSP labs

Compact, breadboard-friendly board built around Microchip’s
dsPIC30F4011 (DIP-40). Ideal for university courses and hobbyists who need a low-cost, fully-THT solution for real-time DSP, motor-control, or instrumentation projects.

Key Features (Rev D)

Block	Details
Power	12 V DC barrel jack → on-board 5 V LDO (LM7805)
CPU	dsPIC30F4011, 30 MIPS, socket pads widened for easy solder/rework
Clock	precise UART/DSP timing
Reset	Single RC + Schmitt trigger → faster boot, ~50 % parts count cut
ICSP	Standard 6-pin header (Pickit 3/4 compatible)
Service	Bridge jumpers isolate power, ICSP, and analog rails → safe bring-up / troubleshooting
Silkscreen	Pin name on every MCU pad + labelled test points
Form Factor	52 mm × 45 mm PCB (≈18 % smaller than Rev B) — fits 70 mm breadboards

Full schematic, 3-D renders, PDFs, and Gerbers live in /hardware/Rev_D/.

Hardware Revisions

Rev	Focus	Major Changes
B	First production	Base THT design, 12 V→5 V regulation, full silkscreen
C	Bug-fix & size reduction	Fixed reversed barrel polarity, wired V_REF±; PCB shrunk 63 × 52 mm → 52 × 45 mm
D	Serviceability & accuracy	Simplified reset, larger socket pads, bridge jumpers, crystal oscillator added

Older spins remain for reference; Rev D is the recommended build.

Quick Start

1 · Clone & Open Hardware

bash

git clone https://github.com/<your-org>/dsPIC30F4011-THT.git
cd dsPIC30F4011-THT/hardware/Rev_D
kicad Rev_D.kicad_pro    # KiCad ≥ 8.0

2 · Generate Gerbers

KiCad → File ▸ Plot → select Gerber + Drill; zip and send to JLCPCB / PCBWay / OSH Park.

3 · Assemble

All parts are through-hole; ideal for hand-soldering or wave machines. Tip : keep bridge jumpers open on first power-up.

4 · Flash the Demo

Questions

How big is the Dspic30 simple PCB?

It measures 95.5 × 57 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Dspic30 simple use?

23 parts, built around the PIC18F4550-I/PT, L7805 and 1N4148WT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Dspic30 simple KiCad files?

From the Esdras2/dspic30f-devboard-kit repository on GitHub, at the commit this page was made from: the board is dspic30_simple.kicad_pcb and its schematic dspic30_simple.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Dspic30 simple design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
