The sample frequency can be set up to 192 kHz.

DC Power

The 96Boards specification mandates power to be provided in one of the following ways :

  • 8V to 18V supply from a dedicated DC jack
  • 8V to 18V supply from the SYS_DCIN pins on the Low Speed Expansion Connector

There is no Type C USB on the B2260 Development board.
The B2260 Development board achieves the requirement and extends the range from 4.2 to 18V.

Power Measurement

The total board power consumption can be measured thanks to the low ohmic resistor R575 located at the left side of the DC Jack connector.

External Fan Connection

Dedicated power supply, 5V and 12V, are provided on the Low speed connector to enable the connection of any 5V or 12V Fan.

UART

The 96Boards specification requires one SoC UART and an optional second UART, both of them will be routed to the Low Speed Expansion Connector.

The B2260 boards meets those two requirements, and the UART 0 and UART 1 can be accessed directly on the Low Speed Expansion Connector. Please see Low Speed Expansion Connector table for more information.**

Buttons

The 96Boards specify the present of two buttons, a Power on/sleep button and a Reset button.

The B2260 Development Board presents only one button. The power on button is not necessary because when B2260 Development Board is supplied, the board boots automatically.
The RESET signals is also routed to the Low Speed Expansion connector.

One button is available for Board Reset, the connector J1 (component 12 of Key Components section). The user will press one second on this button to reset the Board.

LED Indicators

The 96Boards specify for six LEDs to be implemented on the board. The specification defines the LEDs color and mechanical location on the board. All the LEDs are driven by the B2260 Development Board GPIOs.

The B2260 Development Board has two activity LEDs for WiFi and BT activities and four user LEDS.

Two activity LEDs

They are located between the micro USB connector and the USB A connector:

  • WiFi activity LED Yellow, driven by PIO4-0.
  • BT activity LED Blue, driven by PIO3-3.

Four User LEDs

They are located between the two USB type A connectors:

  • User Led Green 1 driven by PIO1-3
  • User Led Green 2 driven by PIO4-1
  • User Led Green 3 driven by PIO2-1
  • User Led Green 4 driven by PIO2-5

JTAG

The 96Boards specification does not call for a dedicated JTAG connector. However the B2260 Development Board has JTAG signal routed to J2.
The J2 connector has a standard 10 pins JTAG connector pitch and is populated on the board as follow.

Power Management Overview

Block Diagram

DC Power Input

The power is provided to the system by 5 power Bucks (identified by DC/DC boxes on the scheme above) :

  • one for the 5V,
  • one for the 3.3V,
  • one for the CPU,
  • one for the Core,
  • one for the LMI domain.

The 1.8V is provided by an LDO that use the 3.3V. All the Bucks operated immediately when the DC power is applied on the CN5 Jack or on SYSTEM_12V_DCIN pins on the Low Speed connector.

Power Source Selection and Sequencing

B2260 Development Board doesn’t propose any power selection scenario.

Therefore the user should never apply at the same time power on the board from the Low Speed Expansion connector (only the SYS_DCIN_12V) and from the DC jack CN5.

Please note that on the B2260 Development Board, the power can be as lower as 4.2V

Voltage Rails

Please note that there is no independent power domain on the B2260 Development Board therefore no power sequencing. When the SYS_DCIN_12V is powered from 4.2V to 18V, all the Bucks will operate therefore feeding all powers domains.
