ptr8500 is a high-performance embedded wireless module produced by sunstar company. it has 4-way 12bit adc, pwm, uart, spi and other rich peripherals, which can be widely used in various types of embedded applications.
The PTR8500 wireless module integrates a high‑performance 51‑microcontroller with RF transceiver functions. It supports 4‑channel 12‑bit ADC, PWM, UART and SPI, making it suitable for a wide range of embedded applications such as remote control, data acquisition, and wireless sensor networks.
Key features include multi‑band operation (430/868/915 MHz), low‑voltage supply (1.9‑3.6 V), standby current as low as 2 µA, maximum transmit power of +10 dBm, and robust GFSK modulation with optional frequency hopping. The module also provides carrier‑monitor, address‑match and data‑ready outputs, and a built‑in CRC‑checked multi‑address protocol. This manual is written in Chinese.
