You get a Matrix of 2 identical boards

(NOTE: Bare PCB board only. No components supplied or fitted)

Does your design end up looking like a birds nest? Issues with reliability and signal noise due to trailing wires? Tired of rubbish ‘EVAL’ boards when all you want to do is get at the micro pins?

“Prototype your own application-specific microcontroller mini-module module – with prototyping area for housekeeping, SMT and through-hole components”

Suitable for ANY microcontroller with a matching LQFP footprint, including the STM32

Seriously, this does it all... Key features below...

• Quality PCB with GOLD plated finish. Precision flat pads give better pin contact for easier soldering
• All 100 micro pins connect to a dedicated pad on the prototype area.
• Route 0V and 3V3 to ANY micro pin using simple solder bridges. No wires
• All pins have a dedicated ‘no-fit’ for a decoupling capacitor. No wires
• Use the prototype areas for mounting crystals or any other housekeeping you care to think of
• Onboard regulator: Derive micro 3V3 from UART, USB or debugger 5V. Connects to a dedicated 0V and 3V3 outer power loop
• Prototype areas accept both SMT and through-hole components
• Additional SMT ICs can be soldered directly to the prototype pads: Supported pin pitches: 1.27mm (½”), 0.65mm and 0.5mm
• Solder Winbond FLASH, connectors, LEDs, sensors, SRAM, precision DAC and ADCs directly the prototype areas
• I/O signal conditioning filter block on all pins: can be configured as high pass, low pass clamps and more.. Use is optional. See images for annotated layout and circuit diagram.
• TWO connection points per micro pins when fitted with a double row header. Great for connecting a logic analyser or patching the signal into another micro pin.
• ETM TRACE connection for high-speed debugging with I-Jet or Segger J-Trace. (STM32 pins 1-5 provided for easy access)
• Scope clip ground and a probe point next to every micro pin. Useful for checking high-speed signal integrity / termination.
• Full pin numbering silkscreen for ALL LQFP package types

For easier and cleaner prototyping. Without modification ALL pins of the device are connected directly to the header. Use as a standard breakout board for any LQFP device.

LQFP package size Will accept any wide or narrow body package: Pitch 0.5mm 48/64/80/100 pin device

Ideal for

• Housekeeping: Add on-board decoupling caps, crystals, voltage references, diode clamps, TVS
• Analog low noise: Add inline filtering components close to IC pins
• Digital high speed: Add series or parallel termination close to the IC pins

Features Prototyping area - Double-sided! Ideal for both SMT and through-hole components. - Extend your design with diodes, caps, regulators, XTALs and more - Plated vias allow signals to be passed from one side of the board to another - Easily route any of the 0.1" pin headers OR device pins directly to pads in the prototype area with the simple solder bridge links. - Pad pitch is 0.1"x0.05" or 100mil x 50mil AND a smaller 2.0x2.0mm area

0V / 3V3 distribution loops

Avoid the usual mess of power connections by using just solder links - Connect any micro pin directly to 0V or 3V3 loops provided. There's even a scope clip area - no more clipping onto the pin headers, it never stays!

Flexible pin re-routing options

Each pin header has multiple solder bridge options to allow for routing to the prototype area - or to ground. A single-track cut option also allows the pin header and the IC pin to be routed separately. There are too many use cases to list here - study the layout and you'll start to see the number of possibilities.

A filter on every pin!

And so much more besides.. Each pin has a provision for two 0805 or 0603 devices. One is located on the top side, the other on the underside. (The topside will also accept a through-hole device) These can be used for decoupling caps, current limiting series resistor, pull-up, pull-down, series termination, parallel termination, clamping, TVS, high-pass filter, low-pass filter - and many others besides. Study the image of the layout and schematic to discover the possibilities.
