flow through these lines. Auxiliary voltage outputs Iono RP D16 has an auxiliary 5 Vdc voltage output pin on the terminal block, labeled 5VOUT, to supply power to external 1-Wire devices or other low-power loads. This output implements an overcurrent protection circuit, with a typical maximum current of 420 mA. -
Page 12: D1-D16 Digital Outputs
Refer to the MAX22190 data sheet for the complete specifications of the digital input lines. D1-D16 digital outputs Iono RP D16 has two banks of 24 V outputs that can be configured as high-side switches or push-pull drivers for high-speed switching, based on two MAX14912/MAX14913 integrated circuits, connected to D1-D8 and D9-D16 terminals. -
Page 13: Overvoltage Protection
NOTICE You should limit the voltage applied to the DT1-DT4 between +0 V and +5 V (TTL level). Exceeding this voltage range will result in damage to the RP2040 board and Iono RP D16. RS-485 serial port Iono RP D16 uses the RP2040 UART0 TX/RX pins (GPIO16 and GPIO17 respectively) to implement a standard RS-485 serial port. - Page 14 You should set GPIO14 low to enable transmission on the RS-485, and set it high to allow reception of incoming data. If GPIO14 is left high, or not configured as output during transmission, the Iono RP D16 RS-485 driver will automatically drive the RS-485 lines in the dominant state, so that it is not strictly required to control GPIO14 in order to transmit data.

ON LED control The ON LED is normally on when the Iono RP D16 is powered, but it is also possible to control it from the RP2040 using the SPI CS (chip select) lines, as shown in the circuit diagram below. -
Page 16: Mapping
Mapping The following table shows the mapping of the inputs and outputs of the Iono RP D16 module to the related pins of the RP2040 microcontroller. Iono RP D16 inputs and outputs RP2040 pins 38 (GPIO26) 39 (GPIO27) 40 (GPIO28) -
Page 17: Hardware Installation
The case also needs to be opened to change the factory configuration of the internal jumpers for the RS-485 termination resistors. NOTICE Before opening the Iono RP D16 case, disconnect all power sources and any connection to external devices. Opening the case Follow these steps, in the exact order, to open the case: 1. - Page 18 Either method will safely discharge static electricity that's naturally present in your body. When handling the Iono RP D16 circuit boards, be sure to hold them along the side edges using your thumb and index finger. Avoid touching the components and pin connectors as damage may occur.

Page 19: Software Development
Iono RP D16 features the same programming interfaces of the Pico board: USB and SWD. USB interface The simplest way to program Iono RP D16 is by connecting it to a computer via USB, then dragging and dropping a program file onto it or using your IDE's features. -
Page 20: Swd Interface
Programming Iono RP D16 via USB does not require it to be connected to a power supply, but when powered only though USB most of Iono's I/O will not be functional. SWD interface Serial Wire Debug (SWD) is a standard interface on Cortex-M-based microcontrollers, which the host computer can use to reset the board, load code into flash, set the code... -
Page 21: Optional Components
The battery is only used to power the RTC chip when the main power is not available. Depending on operating conditions it should last up to two years if the Iono RP D16 board is not powered, more if the Iono RP D16 receives external power. -

NOTICE Before opening the Iono RP D16 Base case, disconnect all power sources and any connection to external devices, including USB cables. Use a non-conductive pin or small tool to help extract the battery from its holder. Insert the new battery with a gentle push. You don't need tools to insert the battery. The battery is held into place by a spring contact. -
Page 23: Earthquake Sensor Module
Earthquake sensor module Iono RP D16 can be shipped with an optional, factory-installed earthquake sensor module based on the OMRON D7S vibration sensor. It is connected to the RP2040 via the I C bus I2C0, GPIO0 (SDA) and GPIO1 (SCL), address: 0x55. -
