MPAINO Series
MPAINO Series is a modular industrial Arduino family that controls digital I/O, analog I/O, temperature sensor inputs, and high-speed pulse I/O using Arduino IDE (Arduino C/C++) or MPINO STUDIO 2 (Arduino C/C++ & ladder logic).
Select a CPU module, I/O modules, and optional modules to configure the product. The product is assembled and shipped in the selected configuration.
Supports 1 RS-232 channel, 1 RS-485 channel, and 1 UART channel.
How to read model names
- The leading number in
8A,16A, etc. is the number of digital inputs. - The number before
Ris the number of relay outputs. - The number before
Tis the number of transistor outputs. 16A16Ris a model with 16 digital inputs and 16 relay outputs.16A16Tis a model with 16 digital inputs and 16 transistor outputs.

Optional modules
The following optional modules can be added to the product configuration. The product is assembled and shipped in the selected configuration.
Users cannot add or remove I/O modules or optional modules.
| Code | Function | Points per module | Maximum configuration | Key features |
|---|---|---|---|---|
| X · Details | Analog inputs | 4 points | Up to 5 units, 20 points | ADS1118 Select DC 0~5V / 0~10V / 0(4)~20mA / NTC input |
| F · Details | PT100Ω temperature sensor input | 4 points | Up to 5 units, 20 points | ADS1118 2-wire or 3-wire PT100Ω input |
| Y · Details | Analog outputs | 3 points | Up to 4 units, 12 points | PWM smoothing Select DC 0~5V / 0~10V / 0(4)~20mA output |
| K · Details | High-speed pulse outputs | 6 points | Up to 2 units, 12 points | Direct MCU PWM signal output |
The combined total of analog inputs and PT100Ω temperature sensor inputs cannot exceed 20 points.
The combined total of analog outputs and high-speed pulse outputs cannot exceed 12 points.
Products with optional modules are custom-built, so exchanges or refunds may be difficult.

PWM0–PWM5 on the K2 image are terminal labels on the second K module. Its additional program channels are 6–11.
Logical channel numbers
The MPAINO core maps logical numbers to physical MCU pins so customers can use numbering in module order.
| Function | User number | Notes |
|---|---|---|
| Digital inputs | From 0 | Use consecutive numbers up to the product's input count |
| Digital outputs | From 64 | R: relay outputs; T: transistor outputs |
| Analog Input X | 0~19 | Available range depends on module count |
| Analog Output Y | 0~11 | Available range depends on module count |
| PT100 Input F | 0~19 | F~F5 logical channels |
// MPAINO-8A8R example: control the first relay output with the first input const uint8_t inputChannel = 0; const uint8_t outputChannel = 64; void setup() { pinMode(inputChannel, INPUT); pinMode(outputChannel, OUTPUT); } void loop() { digitalWrite(outputChannel, digitalRead(inputChannel)); }
On MPAINO, digitalPinToInterrupt(2) refers to the SDA interrupt, not digital input 2. For external interrupts, check the MPAINO-specific logical numbers 0~3.
