We understand that through-hole designs are still needed. We also know how valuable breadboard-friendly products can be. Today, we are announcing 4 new products for NETMF with a through-hole footprint!
Key design goals of these devices are:
[ul]Bread-board friendly.
Most signals from the core are exposed on 0.1" single row headers.
All signals are labeled right on the board, for easier connections.
Contains everything to run. Only requires a 3.3V power source, even if a USB cable is being used.
Includes the RTC crystal and circuitry.
Micro USB connection for easier prototyping but USB signals are still exposed.
GXP-compatible connections for devices with TFT display support.[/ul]
Having the GXP-compatible connection allows for easier connections to displays. For example, the GXP Gadgeteer bridge can be used to connect any Gadgeteer display to any TH board with GXP connections.
Finally, the new TH line of products replaces all older HDR products. All current HDR products will continue to be offered until the end of 2015. We highly recommend the switch to the new TH product line. For those who bought the recent G30HDR, no need to worry this board will be continued to be software supported for the next several years as it is based on the G30 SoC.
it’s going to be a bit nit-picky I guess, but for the G30/80 it might have been a good idea to have half-moon castellations on the sides so you could potentially solder them down to another carrier PCB for more permanent installation. Quicker and easier than buying a raw chip and creating all the necessary circuitry around the board… maybe for the 1.1 PCB?
Uh, oh… Sounds like an Apple move. In six months the G30TH will be replaced with the G30-OTH. Thinner, lighter, and with GHI patented “omni thru-holes”!
The G30 module is now my favorite new board; All we need is a solid W5500 driver and a solid ESP8266 driver, and we’re ready to go. For $15 per, it’s unbeatable. Excellent work, GHI.
The castellations would be nice for mounting the board permanantly, but they might make it hard to use in an actual breadboard; I’ve never tried to solder a header into castellations.
A via may be at the edge of the board so that it is cut in half when the board is separated; this is known as a castellated hole and is used for a variety of reasons, including allowing one PCB to be soldered to another in a stack. - wikipedia
You can have two header holes, the full ones where they are today, and the half-moon ones slightly outside them. Like Justin’s Oxygen has. Perfect for soldering normal headers to so it can be used on the breadboard, and easy to solder down if/when needed
Yes, it would have cost more, but probably pennies in the scheme of things. Little bit more PCB material and a few more drill hits and PTH.
