This document shows the documentation for the Rhomb.io S100 – Headers v1.0 Module.
The S100 – Headers v1.0 Module is a Rhomb.io platform compatible module created to modify and condition the signals of other modules. It works as the interface between two modules which have two different voltage levels. The connection between the signals' supplier and the signals' receiver is done by four connectors: two Headers with twenty pins each one, and the Rhomb.io standard connectors(one receptacle and one plug connector of fifty pins each one). It includes three Voltage Translators (FXMA108), which are used to reconfigure some signals voltage.

The "S100 – Headers v1.0 Module" is a module that allows the connection between modules that were not able to be connected. When the voltage of the signals is high or low and needs to be conditioned, the " S100 – Headers v1.0 Module" can be used to modify it between a range that depends on the FXMA108. In the "S100 – Headers v1.0 Module", the voltage range is as high as 5,5V to as low as 1,65V. It is important to mention that the FXMA108 used in the "S100 – Headers v1.0 Module" are bi-directional, so this module can be used even if it is needed to modify the A port tracks level or the B port tracks level.
Regarding the power supply, two main sources are used: DVCC and VIO_IN. To supply "DVCC" we can use "3V3", "2V8", "1V8", "VIO_IN", "VIN_REG", "VBAT" or "VSYS". All of these power supplies, come from the Rhomb.io module connectors as it is shown in the Block Diagram. By default "DVCC" is not connected to any power source. You can connect "DVCC" by using one of the headers. "VIO_IN" is a power source that comes from the Rhomb.io module connectors. The power sources' configuration should be carried out on the Rhomb.io core. Here it is the Block Diagram of the S100 – Headers v1.0 Module :
Three serial communication ports are used on the module: UART, SPI and I2C. Before being connected to the headers, all of them go through the voltage translators. We can choose the output voltage depending on "DVCC". There are other ports : CAN, CAPT, AD and USB, which are connected directly to the headers.
The next figure identifies the main parts of the S100 – Headers v1.0 Module. It can be found specific information for some of those parts on the following sections.
There are two headers in the "S100 – Headers v1.0 Module". They are used to connect the signals that have been conditioned. Each Header has twenty pins. Both of the headers are Female socket connectors.
- Their operating Temperature has a range between -40ºC and 125ºC.
- The Pitch Mating and Row Spacing- Mating is 0,100"(2,54mm).
- 3 A current rating per contact.
- UL Flammability Rating: 94V-O
- Insulator: Nylon 6-T/Polyester
- Contact Material: Phosphor Bronze
- Termination Type: 2 row SMT
- Mounting Type: SMT, 2 row without guide pins
In the "S100 – Headers v1.0 Module" the signals: SPI, UART, PWM, GPIO, I2C, CAPT, CAN, AD, RESET, 1WIRE, USB, VSYS, VBAT, 3V3, 2V8, 1V8, VIO_IN, VIN_REG, have the next pin configuration:
-HEADER 1 (H1)
NOTE: It is important to mention, that the signals configured as outputs (OUT) in the table, are the signals that come from the Voltage translators. But the FXMA108 are Bi-directional, so these singals could work as inputs.
The FXMA108 is a configurable dual-voltage supply translator designed for both unidirectional and bi-directional voltage translation between two logic levels. The device allows translation between voltages as high as 5.5V to as low as 1.65V. The A port tracks the VCCA level and the B port tracks the VCCB level.
- Bi-directional Interface
- Fully Configurable: Inputs and Outputs Track VCC
- Non-Preferential Power-Up; Either VCC may be Powered-Up first
- Outputs Remain in 3-State Until Active VCC Level is Reached
- Outputs Switch to 3-state if Either VCC is at GND
- 80 Mbps Throughput when translatin between 2.5V and 5.0V
- Cell Phones
- Digital Camera
- Portable GPS
In the "S100 – Headers v1.0 Module" there are three voltage translators to configurate some of the signals used in the module: SPI, UART, PWM, GPIO, I2C.
Each one has 20 pins, which configuration is shown in the next table:
-VOLTAGE TRANSLATOR 1 (U1)
-VOLTAGE TRANSLATOR 2 (U3)
-VOLTAGE TRANSLATOR 3 (U4)
NOTE: It is important to mention, that the signals configured as outputs (OUT) in the table, are the signals that come from the Voltage translators. The signals configured as inputs (IN) in the table, are the signals that come from the Rhomb.io connectors. The FXMA108 are Bi-directional so the Output signals can work as well as inputs, and the inputs as well as outputs.
There is one solder jumper in the "S100 – Headers v1.0 Module". It is used to connect de I2C pull-up. It is not soldered because the FXMA108 has bus-hold circuits. Pull-up or pull-down resistors are not recommended because they interfere with the output state. The current through these resistors may exceed the hold drive, II(HOLD) and/or II(OD) bus-hold currents. The bus-hold feature eliminates the need of extra resistors.
The DS28E05 is a 112-byte user-programmable EEPROM organized as 7 pages of 16 bytes each. Memory pages can be individually set to write protected or EPROM emulation mode through protection byte settings. Each part has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip.

- Precaution against Electrostatic Discharge. When handling Rhomb.io products, ensure that the environment is protected against static electricity. Follow the next recommendations:
- The users should wear anti-static clothing and use earth band when manipulating the device.
- All objects that come in direct contact with devices should be made of materials that do not produce static electricity that would cause damage.
- Equipment and work table must be earthed.
- 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.
