I have one of the boards with the F_CS pin and I was naturally curious if anyone knew the model/type of flash chip which COULD be used on this board - I'm doing a project which indexes arrays of ~a couple hundred thousand strings, which doesn't need gigs and gigs of memory but requires more than...

Thank you, Paul. I will be making these updates presently. :-) I do hope that SparkFun is able to make the updates to the board. Since the Eagle files are available on their site, I am considering making the updates myself (with the benefit of your suggestions above) and seeing about having a...

Thank you for this information, Paul - that is indeed difficult to hear. I'm going to take a hard look at the hardware requirements for my project and start considering some workarounds (some of which may not be so pretty as I'd like). Your time and effort spent on this is greatly appreciated!

FYI: Until further notice, there are no more Arduino.cc Ethernet R3 shields being manufactured, nor are they working on a new shield. For best and most assured compatibility with Teensy hardware, the Wiz820io is the hardware of choice.

Ran into a major snag - according to my recent contact of Arduino.cc regarding the Ethernet R3 shield: the Arduino Ethernet is currently out of production and I have no estimated time for its availability. :confused: :confused:

You'll get no argument from me on that! Its one of the reasons that I am adapting Arduino hardware for control by Teensy. :-) I worked with Arduino UNO units for about a month before I learned of Teensy3. I bought my first unit a week after and haven't been inclined to shift back at all in the...

Knowing that there's an "Arduino.org" that makes their own hardware explains a lot... The more I look around, the more I wonder how those of us without genius-level electronics knowledge (and a touch of OCD) can competently differentiate between all of these products, makers, and specs. Still...

Double-checking prior to purchase: this is the official Arduino Ethernet R3 board?

@Headroom: the suggestion is much appreciated and I will definitely look into this in the future, but this project also needs to interface with other Arduino-standard shields, so the Teensy Adapter board is necessary and there wouldn't be enough vertical clearance to mount the WIZ820io and SD...

This board doesn't have any maker markings on it, but I've managed to identify it as a RioRand (TM) Upgraded Ethernet Shield W5100 for Arduino UNO R3. It's tricky picking genuine hardware out of a lineup unless you know what to look for (thx for the description), and I'm personally not too...

FYI: This datasheet for the adapter shows its schematic and pin mapping.

HARDWARE: I've started work on a Teensy3-based project that interfaces with a W5100 Ethernet Shield by using a Teensy Arduino Shield Adapter. The crystal (DigiKey 300-1002-ND) was soldered to the Teensy, the adapter board was properly assembled, and I've soldered the Teensy+crystal to the...

Thanks, Paul - setting the SD parameters hit the nail on the head. :-) Thank you for answering my n00b question - I appreciate your genius, your products, and all of the work you do.

A few notes on my setup: I'm using a SanDisk Ultra SDHC 8GB card with no other files on it - newly opened 3 hours ago. The Audio adapter and Teensy 3.2 are both new and neatly soldered. I am using the line out instead of the headphone jack as the input to an amplifier which is powering a...

I just want an exceptionally simple WAV player, however, neither the sample files for the sample wav player nor the file I have created seem to be accessible on any of 3 cards I have purchased, formatted, and swapped out. Can someone do me a huge favor and simply spot-check my code - its late...
