The CJMCU-1286 is a compact PIC16F1823 development board built around Microchip’s enhanced mid-range 8-bit microcontroller, designed as a minimum system platform for industrial, robotics, and educational projects. The board operates from a wide 1.8V to 5.5V DC supply, making it compatible with both 3.3V and 5V logic systems, and measures only 21mm × 21mm × 5mm for easy integration into space-constrained enclosures. At its core, the PIC16F1823 provides 3.5KB of Flash program memory, 128 bytes of RAM, and 256 bytes of EEPROM, running on a factory-calibrated 32MHz internal oscillator with software-selectable frequencies from 31kHz to 32MHz. The enhanced mid-range CPU executes 49 single-cycle instructions (except branches) and includes a 16-level deep hardware stack with optional overflow/underflow reset, interrupt capability with automatic context saving, and direct, indirect, and relative addressing modes with two full 16-bit File Select Registers. Peripheral integration includes an 8-channel 10-bit ADC with voltage reference, two analog comparators, an enhanced capture/compare/PWM (ECCP) module, a data signal modulator, MI2C/SPI/EUSART with auto baud, two 8-bit timers (TMR0/TMR2), one 16-bit timer (TMR1), an extended watchdog timer, brown-out reset, and in-circuit serial programming (ICSP) with on-board in-circuit debug. The board also supports Microchip’s integrated capacitive mTouch sensing module. With standby current as low as 20nA at 1.8V and a 25mA source/sink current capability per I/O, the PIC16F1823 development board suits low-power, long-duration, and precision control applications.

Application

  1. Educational and university projects for learning 8-bit PIC microcontroller programming and embedded system design.
  2. Robotics control platforms for managing sensors, motors, and peripheral modules with the PIC16F1823 development board.
  3. Industrial prototyping and automation requiring a compact minimum system board with wide 1.8-5.5V operation.
  4. Low-power battery-operated devices leveraging the 20nA standby current and XLP technology.
  5. Capacitive touch interface development using the integrated mTouch sensing module.
