SOIC28 Breakout

After the TQFP32 Breakout board now a SOIC28 Breakout board. You can fit 14x 0805 components on it, 2x SOT23-6 (or SOT23 or SOT23-5) components, 2x SMD Ellectrolytic Capacitors, 1x Crystal with accompanying capacitors.

More and more IC's are no longer manufactured in DIL housing but only in SMD. There are simple breakout board to solder these SMD IC's in for instance to use them on a breadboard or to be used with prototype boards. But then? Almost every IC needs some external components, one or more decoupling capacitors, pullup resistors for the reset. Fallback on through hole capacitors and resistors? To solve this problem within MEEPS this TQFP32 Breakout board was designed. You can fit a staggering 15x 0805 components, 2x SOT23-6 (or SOT23 or SOT23-5) components, 2x SMD Electrolytic Capacitors, 1x Crystal with accompanying capacitors. A microcontroller like the ATmega328 can be easily mounted on it together with alle needed extra components. Loyal MEEPS users will nitice that the 1mm pins are replaced by normal headerstrips. For use on SMD boards the 1mm pins simply were too big. The needed connectors for these headerpins are available in the Meeps & Parts webstore.


The ATtiny2313 is the last version of a whole series of AVR microcontrollers made by Atmel. Predecessors were for example the AT89C2051, the AT89S2051 and the AT90S1200. It is despite it's small size a very complete microcontroller and it's equipped with a serial port which is also suitable for USB. The MEEPS ATtiny2313 board is equipped with reset circuitry, an external 20MHz crystal and a 6 pin ISP connection to program the microcontroller. A mere 13 I/O pins are free for several purposes. Is the serial port unused the total of free pins is 15, very impressive for such a small microcontroller. The ATtiny2313 is easily programmable in assembly, C en also the powerful BASIC compiler BASCOM AVR is very suitable for this chip. This board is also suited for the recent ATtiny4313, this microcontroller is identical to the ATtiny2313 but has 4K program memory.


Even MEEPS doesn't escape from the traditional protoboard. The Protoboard contains 19x21 solder pads with 1mm holes, more than enough for a lot of purposes. The PCB is doublesided and plated through for mechanical sturdyness, the solder pads won't let loose even after a couple of times of soldering. This PCB is also gold plated so it won't corrode. On customer demand we changed the MEEPS formfactor a bit, this PCB contains 4 0.1" mounting holes.
