switch 8 & 19 are the optical switches

These switch caps are a tight fit.

Line them up carefully then solder.

NHD-3.12-25664UCY2

Mfr.:Newhaven Display
Description:OLED Displays & Accessories OLED 256 x 64 Yellow 89.2 x 44.0 x 6.0
6mm spacers

Audio JacksThese are for the MIDI connectors

Next, proceed with populating all the LEDs. Note that the shortest leg goes into the rectangular pad. 

You're almost there. Now its time for the firmware.

The microcontroller that you need to flash is a ARM STM32f405

Download the latest firmware from the Github Releases page and use the flasher of your choice. 

Both bootloader.hex and sequencer.hex need to be downloaded and flashed to run the sequencer. There is also tester.hex, a hardware test application that can be used to fully test all hardware components.

Use the serial or the JTAG ports.

Firmware

The first method is to use a FTDI Serial adapter

 This has 6 pins

 You need something like this:

The FTDI-Adapter is a USB-Serial bridge. 

It allows you to upload programs to your microcontroller through your PC's USB port. 

The pinout is standard [ GND - CTS - VCC - TX - RX - RTS ] and will work with any Arduino clone that has this as a programming interface.

FT232RL FTDI USB 3.3V 5.5V to TTL Serial Adapter Module for Arduino FT232

or

5V / 3.3V FTDI FT232RL USB to TTL Serial Converter Adapter

 

The IC is a FT232 (Future technology) 

RXD/TXD transceiver communication indicator

Pin definition: DTR,RXD,TX,VCC,CTS,GND

 

or 

If you decide to use the JTAG connector you will need a 

ST-LINK V2 

and an Olimex Arm to JTAG Adapter. 

ARM-JTAG-20-10
