IMPORTANT FOR BULK ORDER LATECOMERS !

This bulk order is officialy closed but I have bought some extra PCBs for latecomers. If you want ones, email me (jeromebo at free dot fr) the quantity you would like and your personal informations:

  • Midibox username
  • Paypal mail address
  • Real name
  • Postal address
  • Country
  • Level of shipping insurance you want to take.

The price of each board is 9€ (I had to buy extra shipping material) and the Paypal fee on the total is 6.5% (with 5% I lost money).

MB-LRE8x2CS PCB / 16 LEDrings/Encoders Control Surface

Welcome to the wiki page of the bulk order of the control surface board featuring combo DINx4 and improved DOUTx4 modules with 16 LEDrings and 16 encoders.

You can find the tread of this bulk order here.

You can find the tread of the PCB design here.

This bulk order concern the last revision of the PCB that is rev 2.4.

The price is 14€ 11€ 9€ 8,50€ each PCB (+ shipping) - This price can be slightly less expensive regarding number of boards ordered -.

It is a very practical and cheap way to make a midi controller with adding only a core or make a more important controller without having to wire LEDrings.

PCB

The PCB have components soldered on the two sides.
Top side: Encoders and LEDs.
Back side: All others components (see BOM below).

The PCB is two sides white silkscreened on green FR4 material, 1.6mm thickness, 1Oz copper, HASL, 100% E-tested & ROHS compliant.

The board is 3,368 x 13,472 inch (342,2mm x 85,5mm): just less than 2U standard.
The diameter of each LEDring is 1,299 inch (33 mm) with the use of 3mm LED.

This is a Mouser Orderlist (Thank you Lamouette). You have only to add your LEDs and Pinheaders.

LED black list

Since Tk discovered a brightness problem with some rectangular 5x2x7mm LEDs, we found it useful to create a list of LEDs wich are successfully or unsuccessfully tested. Members are welcome to edit this page to add their LED feedback.

Components

LEDs & LEDring

Each LEDring is composed of 16 LEDs.
You can use 3mm LEDs or 5x2x7mm rectangular LEDs (because the different angles of the LEDs in the LEDring) or all other LED with 0.1 inch (2,54 mm) leads spacing.
There's not enough space for 5mm LEDs.

LEDring

The LED polarity: the cathode (short leg) has to show to the center of the LED ring:

LED polarity
Encoder

You can use 16mm “standard” encoders (ALPS STEC16, Bourns PEC16-4xxxF-Nxxxx series, encoders sell by voti, …).
You can use instead PEC16-4xxxF-Sxxxx series (with built-in switch). Probably others built-in switch encoders comply the PCB footprint but you have to compare before datasheets.

16 pins SIL header

If you use switched encoders, one of the two pins of the built-in switch is grounded while the other pin is connected to a pin of this SIL connector.

The silkscreen include the name of each switch.

2x5 pins DIL headers

They are 1:1 with J8/J9 of Core8/Core32/LPC17 so you can use practical IDC female Connector or still more easier pre-built 2x5 Pin IDC Ribbon Cable.

Be careful to the connection to the MBHP_CORE_LPC17 module because it could be confusing, since the SO pin of J8/9 has to be connected to the SI pin of the LRE2x8 board, and SI to the SO pin (for MBHP_DOUT/DIN we usually have the same names for these signals, this detail has been overlooked).

ULN2803

This component provide more current to the matrix LED than the 74HC595 shift registers can and improve the brightness of the LEDs.
You can use or not Transistors Darlington arrays.
In the second case (and only in this case), you need to bridge 16 of the 18 free pins 2 by 2 (in red on the picture):

Bridges
Be careful to not bridge the 2 last pins
(those opposite to the “head” of the chip).
DIP switchDIP switch
An idea is to use e.g. DIP16 Switch. (NT 08 at Reichelt).
220 Ohm 16 Pin DIL resistor network

As in the SmashTV's PCB, you can replace a DIL resistor network by 8 resistors.
In this case I recommend to use 1% metal film resistors because with the tolerance of standard carbon resistors you could see maybe different brightness of each LED of the LEDring.

10kOhm 6 Pin SIL resistor network

Be careful when sourcing SIL resistor networks because a 6 Pin SIL resistor network can be 5 commoned resistors (what you need here) or 3 independant resistors.

Polarized Electrolytic Capacitor 100 uF

It is the only polarized cap of the board. The silkscreen indicate the “+” and “-” signs on the board.

Diagram interconnection

One board connection
Diagram interconnection

Only one 2×5 Pin IDC Ribbon Cable is necessary to connect the board.

Global interconnection
Diagram interconnection
You can download a better definition version here.

You can chain 4 of this board or connect yours extra DIN/DOUT modules e.g. on the DIL connector named “OUT”.
You can connect also this board at the end of the chain and connect this board with the “IN” connector after yours others modules.

With the use of the upcoming MIDIbox NG (planned for Winter 2012/13) you will be able to have 2 chains of 4 boards each (2x4x16=128 encoders and 2x4x16=128 LEDrings).

If you take “with insurance” you will be compensated of the amount of the insurance in case of lost of the parcel and your shipment is tracked (until your door in this country: Germany, Belgium, Denmark, Finland, UK, Hong-Kong, Ireland, Japan, Luxembourg, The Netherlands, Slovakia, Sweden, Swiss and until the French frontier for the others country). In any case I receive a proof of delivery.

For (french language) tracking page, it's here. Fill the textbox “Numéro de suivi” with your number.

If you take “without insurance” there's no tracking of the parcel.

If your country is not in this table, or if you want more PCBs, PM or email me.

Bulk order update

As many people want some onboard components and as resistor networks (SIL and DIL) are not easy to find at good price for few quantity, I add a bulk order only for SIL and DIL resistor networks to this bulk order. Others components (except encoders) are easily “sourcable” on Internet.

I have modified the list with 2 new columns.

Importants informations:

  • I will make the Mouser order the same moment I will order the PCBs.
  • Only member which order PCB(s) can participate (…sorry!).
  • The weight (…and the price) of the shipping of the parcel to each member shouldn't be different (except maybe for 4 boards where the weight was very slightly less than the limit of 0.5kg: But my kitchen food balance say me it should be ok) - Well understood each member doesn't buy to much components! -
  • The price (in euros) of the 652-4116R-1LF-220 and the 264-10K-RC will be the one Mouser propose regarding the quantity ordered for each item.
