BOARD SPECIFICATIONS

The Halley board has been designed for working only with rhomb.io modules. Three standard rhomb.io modules holders are available, one for the master module and two for the slaves. That brings simplicity and speed up the product designing and development stage.

There are two different ways to empower the system: using the micro-USB connector or a battery. The PCB also includes a Lithium battery charge management controller bringing the capacity to work independently of the power supply.

As a summary, here are the key features for the Halley board:

  • Capacity for holding three rhomb.io modules: Master and Slave (x2)
  • Fast prototyping
  • USB connector for data and power supply
  • In-circuit battery management
  • Small form factor

The block diagram shows the parts that make it possible.

WIRELESS

The Halley board has nos wireless interfaces.

VIDEO/AUDIO

The Halley board includes the SAI-A port. This makes it possible to connect an Audio Module. Even so, these signals are connected to Headers.

The SAI interface (SERIAL AUDIO INTERFACE) is a peripheral supporting a wide set of audio protocols thanks to its flexible architecture:

  • I2S (Inter-IC Sound).
  • I2S LSB or MSB.
  • SPDIF Output.
  • PCM( Pulse Code Modulation).
  • TDM(Time Division Multiplexing).
  • AC’97 (Audio Codec ’97 from Intel).

A SAI embeds two independet audio sub-blocks which can be:

  • Transmitter and/or receiver.
  • Master or Slave.
  • Synchronous or asynchronous mode between the audio sub-blocks.
  • Clock generator for each audio sub-block to target indeendet audio frequency sampling.

Regarding the serial interfaces, three issues should be mentioned:

  • The USB data lines comes from the micro USB type B connector to the J201 master module connector.
  • For the I2C interface, the board provides two pull-up resistors (R4 and R5). Those pull-ups are defined as normally connected to the supply. If you want to disconnect the supply, there is a solder jumper next to the pull-up resistors.
  • Halley board only has two slave modules, so to get the most versatility there is an UART SWITCH device. By default UART-B is MOD2_UART-A, when the switch is activated, UART-B turns into MOD1&2_UART-B in order to be able to control two slave modules with two UART interfaces with a S100 master module.

See the image below:

UART SW.JPG

POWER

The Halley board provides the needed voltages for the rhomb.io sockets. For doing so, Low Dropout Regulators (LDO) has been included for supplying the “1V8”, “2V8” and “3V3” voltages. The “VSYS” voltage is switched in between “5V_USB” and “VBAT” (battery voltage) according to the following cases:

  • There is battery but the USB charger is not connected: VSYS = VBAT
  • There is battery and the USB charger is connected: VSYS = 5V (according to the USB standard)
  • There is no battery and the USB charger is connected: VSYS = 5V (according to the USB standard)
  • There is no battery and the USB charger is not connected: VSYS = 0V

As per the above, the Phobos board can work connected to a USB 5V source or with a battery. In this last case, only single cell Li-Po or Li-Ion batteries are supported. The charging current ranges from 15 to 500 mA. You can adjust it with potentiometer P1 following the next formula:

Ichrg(mA) = 1000V/(2k+P1)ohm

The following table summarizes the power supply signals on the Halley board and indicates where are used.

Signal (Rhomb.io) Voltage (V) Device
5V_USB 5 VSYS rail
VBAT VBAT VSYS rail, Rhomb.io module, H1 pin 13
VSYS 3 – 5.5 Rhomb.io modules, H1 pin 12
3V3 3.3 Rhomb.io modules, H1 pin 9
2V8 2.8 Rhomb.io modules, H1 pin 10
1V8 1.8 Rhomb.io modules, H1 pin 11

To supply the Halley there is also a Header (H4). The Header allows the user to supply the board with a Voltage Range from 7 V to 63 V.

To control such a high voltage the Halley includes a DC/DC, the MAXM17575ALI#.

IO-EXPANDER

The Halley includes an IO Expander, with this device the user is able to control some functions avaliable in the Carrier Board devices by I2C. The IO Expander chosen is the FXL6408. It is an 8-bit I2C-controlled GPIO expander. When configured in Input Mode, the FXL6408 monitos the input ports for data transitions and signals the baseband by asserting the /INT pin.

The input default values can be programmed independently, allowing customized input detection.

When configured in Output mode, the GPIO pins are capable of delivering 6mA output drive according to the I2C register set.

WARRANTY

  • Precaution against Electrostatic Discharge. When handling Rhomb.io products, ensure that the environment is protected against static electricity. Follow the next recommendations:
    1. The users should wear anti-static clothing and use earth band when manipulating the device.
    2. All objects that come in direct contact with devices should be made of materials that do not produce static electricity that would cause damage.
    3. Equipment and work table must be earthed.
    4. Ionizer is recommended to remove electron charge.
  • Contamination. Be sure to use semiconductor products in the environment that may not be exposed to dust or dirt adhesion.
  • Temperature/Humidity. Semiconductor devices are sensitive to environment temperature and humidity. High temperature or humidity may deteriorate semiconductor devices characteristics. Therefore avoid storage or usage in such conditions.
  • Mechanical Shock. Care should be exercised not to apply excessive mechanical shock or force on the connectors and semiconductors devices.
  • Chemical. Do not expose semiconductor device to chemical because reaction to chemical may cause deterioration of device characteristics.
  • Light Protection. In case of non-EMC (Epoxy Molding Compound) package, do not expose semiconductor IC to strong light. It may cause devices malfunction. Some special products which utilize the light or have security function are excepted from this specification.
  • Radioactive, Cosmic and X-ray. Semiconductor devices can be influenced by radioactive, cosmic ray or X-ray. Radioactive, cosmic and X-ray may cause soft error during device operation. Therefore semiconductor devices must be shielded under environment that may be exposed to radioactive, cosmic ray or X-ray.
  • EMS (Electromagnetic Susceptibility). Note that semiconductor devices characteristics may be affected by strong electromagnetic waves or magnetic field during operation.
