MIDI TRS-DIN5 Adapter with TRS-A and TRS-B support DIY kit

Description

When dealing with modern MIDI hardware, very often you have to interface with TRS MIDI cables. Some vendors do include DIN5-TRS adapters with a purchase of hardware, while others don't. Also, you have to remember proper specification TRS-A or TRS-B and keep the corresponding adapter. This small passive adapter is designed to solve this problem. It's handy, it can be easily cased with two acrylic panels and standoffs, as well as it could be mounted inside the enclosure. I'm using special DIN sockets which include mount holes and come with corresponding screws. You can also mount it from the TRS part, as the socket comes with a nut.
You don't need to deal with different adapters for TRS A or B. This board can switch specifications by a jumper.
Board size and an specifications:
Size: 36x37mm = 1.4"x1.45"
This is a complete kit with all ICs, passive components, sockets.
Beginner soldering skills required. That means you have to understand schematics, not just being able to solder two wires together. There are no high expectations, but being able to read schematics and understand polarity of components are quite important.

Shipping:
Item will be shipped by Air Mail on the Same or Next Business day of receiving full payment.
This is international shipping from US. Exact delivery time varies from your location and could be up to 3-5 weeks.
NOTE: Don't be surprised, USPS has increased the shipping cost since Jan 01 2016, so the minimal package costs .50 for the first class international.
Enjoy MIDI Breakout board for your Teensy microcontroller. This board is designed for Teensy4.1 and it's not compatible with other Teensy. If you're looking for similar board for Teensy3.2, Teensy4.0 please, check other products in my store.
The board provides MIDI 8 input / 8 output functionality and USB host. This can be your 8x8 MIDI interface, merger, splitter, filter or whatever else you can imagine. It can also work in conjunction with other USB MIDI class compliant devices. This obviously requires programming Arduino framework with Teensy extensions. Teensy example firmware is provided.
Power is supplied from Teensy, so no external power required.
All Teensy pins are available on extra pin headers. This allows easy expansion if you're planning to add extra LEDs, buttons, OLED display, audio inputs or outputs, etc... You can do that without soldering.
Package options:
This is a DIY Complete Electronics kit: Includes PCB and all electronic but Teensy4.1. Din5 connectors, optocouplers, headers, resistors, diodes, USB socket.
Check BOM list by the link github.com/Deftaudio/Midi-boards/tree/master/MIDITeensy4.1
*Teensy microcontroller is not included with any purchase, you can buy it directly from the manufacturer: https://www.pjrc.com/store/
Board size and an enclosure choice:
Size: 82mmx177mm
Some of you wondered ideas for enclosure selection. I found it much easier to put them in between two acrylic panels cut to the size and connect them with plastic standoffs. I typically use M3 standoff 20mm and 5mm. 20mm goes on top, and has enough room to cover DIN5 sockets, while 5mm goes on the bottom. You can purchase it as optional accessory or make your own. There is CorelDraw file on Github with precise board dimension and holes location.
Please, consider Github page github.com/Deftaudio/Midi-boards/tree/master/MIDITeensy4.1 for sample firmware. And please, watch a video
