Liudr has designed and built a SDI-12 + Analog USB adapter. Project info at Liudr’s blog.
Soynerdito has been working on a small hardware adapter for ESP8266-WIFI Uart module: Idea is to provide a small board to allow connecting the ESP8266 ver ESP02 to a breadboard. It is kept small so the price is cheap. A small batch was ordered to oshpark and waiting for order to arrive to see if the idea works. […]
alexwhittemore has posted a detailed tutorial how to make an adapter: ST-Link/V2 SWD-JTAG adapter The fantastic STM32 Discovery boards from ST Micro all come with an embedded ST-Link/V2 debugger onboard, including some jumpers to disconnect it from the target device for use as a standalone SWD debugger. Presumably, this is to allow for easy use debugging […]
Arthur Guy made this mini LCD backpack for the smaller display screens: This is an LCD backpack but it is for the smaller displays with the double row of pins rather than the single line. I made this adapter as I was working with some small displays and needed a simple way of connecting it to […]
A followup to the GPIB USB Adapter. Steven demonstrates how to use his adapter in two different software environments the Ubuntu 13.10 + Python + InstrumentKit and the Win7 + Terminite. Via the forum.
scasagrande shared his GPIBUSB Adapter rev3 in the project log forum: This past weekend I finally finished up the third major revision of my GPIBUSB adapter board. Major hardware changes include swapping the pull-up resistors for the proper GPIB line drivers, as well as swapping the FT232RL for the newer FT230X. There is a number of software […]
Ethan Zonca of Protofusion writes: While developing the Luma RS485-networked LED driver we discovered a need for a small and inexpensive USB to RS485 adapter. We designed an adapter with a FTDI basic UART chip (FT230XS) and an inexpensive TI differential receiver (SN75176). Our small selection of parts brings the cost down to just over […]
Kerry Wong wrote about building a precision voltage adapter using LTC1100: LTC1100 is a zero-drift, precision instrumentation amplifier. Unlike LMP8358, it does not offer programmatic gain setting (the 8-pin package), and the gain is preset at 100. But LTC1100 has several advantages over LMP8358. For instance, while the typical gain non-linearity for LT1100 and LMP8358 are quite […]
@indigoid tweeted this picture of his DIY adapter for flashing ATtiny84/85 with the Bus Pirate: Very dodgy DIY adapter for flashing ATtiny84/85 via Bus Pirate. Shown w/ ATtiny85. No more jumpers! Get an assembled Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.
The serial UART is a common interface used by many chips and devices. Ginpb designed a USB-to-UART adapter that works with 3.3V and 5V UART signals. The device is based around the FTDI FT232BL USB-to-UART IC with an added 3.3V power supply. The different interface levels are selected by an on-board jumper. Via the forum.
Here’s a quick way to how to adapt an SOIC surface mount chip to replace a through-hole part. You can do this with stuff on your bench: a DIP IC socket, a few wires, and a wood scrap. Beautiful? Heck no. (More like slimy but satisfying.) But finding a way to get your circuit board […]
After posting about SILtheDIL, we received another idea on how to break-out dual row headers. Victzh and Shaos made similar adapters that allow dual row headers to be used with a standard breadboard. They write: “it’s more like “DILtheDIP” or “DIPtheDIL” :)”. Via the forum.
Many development modules come with DIL headers on each side of the board. This makes them totally unusable with a breadboard. To remedy this Arakis built an adapter that converts 2X20 dual row headers to a 40 pin single row of headers . It can either be used to directly stick a module into a […]
MickM built flat cable to header converter adapters : I was using some character LCD displays and realised that the cables were impossible to plug into the displays that I actually had. My PCB was single row of 16, the LCD was 2×7, no backlight. So I made an adapter for it. Via the forum.
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week we’re giving away two […]
Development of the Bus Pirate PIC programmer involves testing a bunch of different chips. This $10 universal programming adapter from Sure Electronics will be really handy. This board doesn’t actually program any chips. It’s an adapter that accepts a lot of different 18-40pin PIC chips and connects the programming pins to a header. The ZIF […]
The Bus Pirate can be used as an ARM JTAG debugger with OpenOCD. Joby Taffey set up the OpenOCD/Bus Pirate tool chain, and used it to work with a Stellaris LM3S9B90 (ARM Cortex-M3). Get a Bus Pirate for $30, including worldwide shipping at Seeed Studio. Adafruit also has the Bus Pirate and probe cables in […]
