Product Details
✓[Wide Compatibility] Supports DMR, P-25, D-Star protocols and system integration. High-performance configuration: Equipped with a 32-bit ARM processor, with RF power up to 10mW, and the product has undergone comprehensive testing. Compatible with all Raspberry Pi models, including Pi 1, 2/2b, 3/3b/3b+, 4/4b, Pi Zero, and Pi Zero 2W
✓[Easy to Assemble] Firmware is pre-loaded and can be easily upgraded via software. Onboard LED indicators display real-time device status (Transmit Tx, Receive Rx, Push-To-Talk PTT, operating mode). Supports Pi-star control mode selection: Duplex Mode / Simple Mode
✓[Frequency Range] Supports UHF band 433-900MHz and VHF band 144-146MHz (including 144-148, 219-225, 420-475 main frequency bands, and 842-950 band). Best suited for amateur bands: 430-440MHz. Note: TX (Transmit) = 0, RX (Receive) = 0. To keep the screen on continuously in Pi-Star settings, ensure "OLED Type 3" is selected in the "Display Type" field at the top of the page, and set the port to: Modem
✓[Setup Instructions] The modem type can be modified (supports any model ending with GPIO). Select Radio/Modem Type as: STM32-DVM/MMDVM_HS-Raspberry Pi Hat (GPIO).
