Get your PIC or other uC talking to your computer fast and easy with this board! This is a small custom PCB developed to connect the UART on a microcontroller directly to the computer without the hassle of a MAX232 circuit. Almost all current computers (less than 10 years old) utilize a serial port based on the EIA-232 standard which operates from +/-3-12V rather than the RS232 standard of +/-12V. This board takes signals from the computer/microcontroller and correctly inverts and amplifies the serial signals to the EIA-232 standard. Works great up to about 38400bps. Originally designed to get Bloader working in a bread-board setup, we use our Shifter at 115200bps without problems.
Comes as a bag of parts kit and is easily assembled if you can follow the silkscreen indicators and have beginning experience with a soldering iron.

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Warning: this kit passes only TX/RX, no handshake lines! Board quality & parts seem OK, but I couldn’t use it.
I failed to notice that it was TX/RX-only looking at the illustration. That’s insufficient for my application, which requires me to be able to pass the 1PPS signal from a bare -wire GPS-18.
A version that can level-shift RTS/CTS/CD/RI would be a big improvement. Even just CD would be enough for a large class of applocations.
Hi, You are correct in that we only make use of the primary communication lines. So sorry that these did not work for your needs. Happy hacking. Thanks.
