MDBT42Q-P512KV2

MDBT42Q-P512KV2 is a compact Bluetooth Low Energy (BLE) module from Raytac, built around Nordic’s nRF52832 SoC. It combines a 32‑bit ARM Cortex‑M4 MCU with a 2.4 GHz BLE radio and ships with 512 KB flash and 64 KB RAM, enabling standalone BLE apps or firmware updates.
Key points:
- BLE 5-capable (2.4 GHz, with features from the Nordic platform)
- Power: 1.7–3.6 V supply
- Interfaces: multiple GPIOs plus common peripherals (UART, SPI, I2C, PWM, ADC)
- Antenna: on-board PCB antenna in the standard variant (with option for external antenna in other variants)
- Package: small SMT module designed for easy integration with minimal external components
- Use cases: wearables, sensors, beacons, IoT devices
V2 denotes revised mechanical/RF characteristics and manufacturing improvements over earlier releases. Documentation, evaluation kits, and reference designs are available from Raytac.

MDBT42Q-P512KV2 is a BLE module based on Nordic nRF52832 (512 KB flash). Equivalents:
- Nordic nRF52832 SoC (bare chip)
- Other nRF52832-based BLE modules with 512 KB flash, e.g., Laird Connectivity BL652
- Raytac MDBT42Q family variants (same silicon, different package/variant)
In short: any 512 KB flash, nRF52832-based BLE module or the bare nRF52832 chip itself.

MDBT42Q-P512KV2 features (concise):

- Memory: 512 KB flash, 64 KB RAM
- 2.4 GHz transceiver: Bluetooth Low Energy, ANT, and 2.4 GHz proprietary protocols
- On-board RF: PCB trace antenna (with RF I/O for alternate antenna options)
- Power: 1.7–3.6 V operation; low-power sleep modes
- I/O and peripherals: up to 32 GPIOs; UART, SPI, I2C, I2S; PWM; timers; RTC
- Analog: SAADC 12-bit with multiple channels
- Debug/programming: SWD/JTAG for easy development
- Temperature range: -40 to +85 °C (industrial)
- Certifications: FCC/CE (per module), RoHS compliant
Notes: exact BLE feature version (e.g., Bluetooth 5.x) depends on SoftDevice/stack; always verify current datasheet for specific protocol support.

- Pin count: 24 pins (two rows of 12 castellated pads).
- Function: Bluetooth Low Energy module (MDBT42Q) built around Nordic nRF52832 with 512 KB flash. It exposes MCU GPIOs and peripherals (UART, SPI, I2C, PWM, ADC, etc.) for easy BLE-enabled integration.
