Simplify Eagle library part creation from BSDL files

Here’s a tutorial on how to automatically generate Eagle parts from manufacturers’ BSDL files. These files are available from some manufacturers and include tables listing pin names and numbers. This information is used by the make-symbol-device-package-bsdl.ulp to generate your device. On our wiki we have a tutorial on how to built devices for your Eagle […]

Eagle Parts: Dual supply 8-Bit bidirectional voltage level translator in TSSOP-20

We added the TXB0108 dual supply 8-bit bidirectional voltage level translator (TSSOP-20 package) to our library. As the title suggests it translates 8 channels between two voltage levels. There is no direction control. All the pins are bi-directional at all times, and the directions of each pin are independent of one another.

Eagle Parts: Folding micro SD card socket and the PIC24F16KA102 microcontroller in SOIC-W and SSOP packages

The latest parts to be added to our Eagle part’s library are the folding micro SD card socket, and the PIC24F16KA102 microcontroller. The symbol for the PIC is connected to the SOIC-28W, and SSOP-28 footprints. Check out a picture of it below.

Eagle Parts: 74XX245 buffer footprint, because Murphy always strikes twice

This part from our Eagle library is a favorite. We use the 74xx245 buffer as a 5v to 3.3V level translator in many of our projects. Many of those projects went through a few revisions, ’cause we keep getting the directional control pin wrong. Eventually we branded a legend for the “DIR” pin directly on […]

Eagle Parts: TD62783 8Ch high voltage source driver and the 2.1mm barrel jack

Latest parts added to our Eagle library are the TD62783 8Ch high voltage source driver and a 2.1mm barrel jack footprint using oblong plated through holes. The TD62783Ch is a 8 channel high side switch, we intend to use it in our VFD boards. Check out the DC barrel jack schematic symbol, and all of […]

Eagle Parts: MIC2027 Quad USB power distribution switch

We added MIC2027 Quad USB power distribution switch to our Eagle library. This part is used to limit the outgoing current to the USB maximum 500mA. In case of a short circuit, an over-current pin for the corresponding channel is raised high. At the same time the device switches to a current limiting mode. This […]

Eagle Parts: INA138 high-side current shunt monitor

We added the INA138 high-side current monitor to our Eagle parts library. This is the part used in the Smoke Tester to read current through a voltmeter. It basically mirrors the current going through its shunt resistor to a load resistor. By playing with these values you can get an easy shunt current to output […]

Eagle Parts: Our Eagle library converted to KiCad

Lately we’ve been testing the KiCad waters. For the ATX Breakout Board v2 we needed to escape Eagle’s PCB constraints, and we succeed. A major hurdle to using any new CAD package is that all your part libraries have to be built again. Luckily Sjaak pointed us to a script that helps you convert your […]

Eagle Parts: FT311D Android Open Accessory host USB IC

We added the recently released FT311D Android Open Accessory host USB IC in a LQFP-32 package to our Eagle library. The device makes it easy to communicate to Android devices using the Android Open Accessory Mode available on Android platforms from 3.1 and up. The reference circuit is pretty simple, like most FTDI chips, we’ll […]

Eagle Parts: TPS6120x DC/DC converter and KSZ8851SN Ethernet controller in a QFN packages

Today we added two relatively hard-to-solder parts to our library. Both come in QFN lead-less packages. First is the Texas Instrument’s TPS6120x DC/DC converter (pictured above)  with an integrated switch. The second is the Micrel KSZ8851SN embedded Ethernet controller (pictured below).

Eagle Parts: Serial 1.8” TFT and 2×10 shrouded header update

Lately we’re playing around with a 1.8” serial interface TFT which can be bought from eBay for ~$6. We added it to our Eagle part library. We also found some errors on the standard Eagle footprint for 2×10 shrouded headers we use in the Bus Blaster v3. Image of the new, fixed shrouded header’s footprint, […]
