Thanks for the details and cautions! I had budgeted last year for the 480 "Plain" or whatever they want to call it, and was somewhat surprised they pitched the "Ultimate" instead.

I am looking for a way to capture, analyze, and time USB traffic for a few specific cases - measurement, not design. Anybody using a Beagle 12 or 480 with Teensy as HID? Pros and cons? My use cases, with analyzer(s) inserted on each <--> USB Host <--> USB HID Device USB Host <--> USB Raw HID...

... and the IDE let's me do that even w/o a Teensy LC attached :) Just ordered mine yesterday. Thanks!

That is cool. This works for both of these I assume? https://www.pjrc.com/store/display_ili9341.html - discontinued https://www.pjrc.com/store/display_ili9341_touch.html I just ordered the latter out of a vague notion of wanting some debug display option on hand.

@PhilB - just FYI, there's a related thread - https://forum.pjrc.com/threads/60846-T4-1-Ethernet-board plus https://www.mouser.com/ProductDetail/Bel-Magnetic-Solutions/0820-1X1T-00-F?qs=sGAEpiMZZMvQhAhQbXdbBhrEwE4Ds1jHaYqXdbGAlwg%3D and...

You know, that is not a bad idea at all! Can't find any explicit confirmation that LC has USB Raw HID and HID https://forum.pjrc.com/threads/59565-USB-Raw-HID but would assume so as bootloader uses it. Have to think about bandwidth on the teensy-to-teensy I2C/serial - Teensy 4.1 not in...

That's useful for part of my needs, thanks! But it does not cover all uses cases :( I always have to connect to two separate USB hosts using two physical connectors. Plus, in one important use case, I *have* to attach another separate USB device to the Teensy 4.1 2nd USB acting as Host. So I...

I'm in need of a USB HID Shield for Teensy 4.1 - not a Host Shield Retail, or github. Yes, I do have two separate USB Hosts that I need to connect to at the same time, from the same Teensy 4.1 I am assuming I cannot use the USB Host adapter (no OTG), plus the Host connector is already spoken...

Yeah, I wasn't expecting castellated solder. Not cutting Teensy edges like some have tried? I already accepted headers so that dead Teensy can be swapped. https://forum.pjrc.com/threads/28847-Request-Castellated-Edges-on-Teensy-3-1-PCB Indeed. My real problem is that that requires me to use...

Trying to figure out some basics about cost, robustness, maintenance, repair in case of deploying hundreds of Teensy boards, to rack mounts. There are two possible approaches: a) make each node a separate Teensy + custom shield/breakout. 3d-print a box for each, or a rack mount box for many...

If anybody has numbers already for a) using Ethernet (with the OSH adapter) (target rate 1kHz UDP packets) b) using USB HID RAW over PJRC Host adapter cable (also 1kHz rate) I'd much appreciate it. I saw chip's rated at <70mA and board was measured <105mA but I'm at a loss with respect to...

Space is not the problem. The problem I started with was having to use separate hub boxes etc. or a custom shield/breakout in the first place. I am basically trying to make sure there is no off-the-shelf MCU, and no off-the-shelf shield for an existing MCU, that could be used. Once I accept...

Yeah, this https://store.arduino.cc/usa/arduino-yun was the closest product I have found so far, so the Teensy 4.1 is just-in-time and very welcome! So breakout / shield for RJ45+Host USB (or carrier PCB for several T41) it will have to be. I must have misread / misremembered...

Thanks guys!
