: You may find this chip marked as RF250A on some drone or toy controller boards. Datasheet and Resources
The datasheet lists 24 GPIOs, 4 PWMs, 3 timers, and an 8-channel 12-bit ADC. Notably missing? USB. This module is unapologetically pure BLE. No USB controller wasting die space. No SPI flash for OTA (you get 192kB onboard, so optimize your code). It forces discipline. pan186cv datasheet new
: 2.4 GHz circuit optimized for high interference suppression and low power consumption Peripherals 8-channel, 8-bit precision Integrated PWM generator, hardware comparator, and timers Low Voltage Reset (LVR) and multiple clock sources Common Use Cases The chip is a staple in the RC hobby community , frequently appearing in: Entry-level RC Planes : Such as the VolantexRC Mini Mustang P-51D V2 Toy Transmitters : Often paired with other RF chips like the CB2401 : You may find this chip marked as
Today, as new developers stumble upon the chip while teardown-ing drones, the is gaining a cult following. While some experts suggest using more documented modules like the ESP32-C3 for new projects, the PAN186 remains a symbol of efficient, low-cost engineering. Panchip Microelectronics Co., Ltd.
