The Olimexino is a cheap and widely available development board
This board is not recommended for cleanflight development because many of the pins needed are not broken out to header pins. A better choice for development is the Port103R, EUSTM32F103RB (F1) or the STM32F3Discovery (F3).

3 way power selector header
1 - VIN 2 - 5V from FTDI 3 - N/C - Jumper Storage
Middle Left
3 way power selector header
1 - VIN 2 - 5V from CP2102 3 - N/C - Jumper Storage
Use either power selector to supply VIN from the serial port adapter sockets, ensure that both power selectors are not enabled at the same time. One or both of the power selector jumpers MUST be in the jumper storage position.

Serial IO & Serial Loopback
Bottom right
The header pins allows combinations of serial loopback and Serial IO. Any amount of connections or jumpers can be used at the same time.

HoTT Telemetry port
When the HoTT enable jumper is on pins 2 and 3 then HoTT data can be received/transmitted on either serial port depending on the placement of the Derial IO selection jumpers.
When not in use the HoTT enable jumper can be stored on pins 3 and 4
The HoTT telemetry is connected to the center pins (2 & 5) of the Serial IO header.
