I am in Michigan (US).

I have 99 Teensy 3.2s available, 28 of them with pins. All still in their original packaging. DM if interested.

Supply voltage is 12V. So I'd be at .7 watts, yeah? I guess I'll take a look at some heat sinks then.

Hi all, I'm making a breakout board for my Teensy 4.0 that will have power supplied to it from an external power supply. I need to add a voltage regulator to get the voltage into the Teensy down to 5V, but I can't figure out what the minimum mA output of the voltage regulator needs to be...

Not rude at all. I'm asking because the example layout in the datasheet shows the transceiver being complimented by a handful of other components, but I've come across images/sketches/videos of people using the transceivers without any compliment of components. As I'm not an Electrical...

With RS485 do I need to include an extra node at the end of the chain that has a termination resistor?

Generally speaking, do the RS485 transceivers connect directly to the 3.3v/GND/Tx/Rx pins on the Teensy and the A/B wires from the master, or are there other components that need to be integrated to make it function properly (resistors/capacitors/diodes,etc)?

If I used the SN65HVD82 I would need to use a Teensy that has 5v tolerant serial pins, correct?

So if I go the RS485 route, can I start testing with a USB to RS485 from my computer to a RS485 to UART at my microcontroller? Does the connection from the RS485 transmitter to the RS485 receiver need to include a ground wire?

If the pins for the input and output are connected to each other then the signal will just bypass the node if it goes bad, right? I'm thinking about it from a wire management standpoint. I'd prefer to have short runs from cell to cell rather than long runs back to a central hub. I'll define...

From a physical wiring standpoint how does this work? Does each microcontroller have an input and an output that just get daisy chained from cell to cell? Is there a preferred connection/wire type?

I've purchased a few Teensy 4.0s for testing, but nothing is set in stone with regards to which one will be used in the final build. Whatever will work, I suppose. The messages will be fairly long. It will be a string of values with an ID tag for each value. Each of the nodes will have an ID...

Hi all, I'm working on a concept that involves controlling an array of stepper motors (up to 100 in a 10x10 grid) at the same time. The idea is that a master controller (could be a pc or another teensy) would send a serial message to be received by a teensy at each of the motor locations and...
