Kurva Suhu Disaranake
Sistem Panganggo Minimal
Modul iki bisa digunakake mung ing 3.3V digunakake voltage:
Cathetan
- Kerja voltage kanggo modul punika DC 3.3V;
- Saiki maksimum saka IO modul iki 12mA;
- Modul Zigbee ing mode download: D28 tingkat dhuwur, banjur modul reset kanggo daya ing;
- Modul Zigbee disambungake menyang RXD saka MCU liyane, lan TXD disambungake menyang RXD saka MCU liyane.
Desain PCB sing Disaranake
- XT-ZB1 modul bisa didol ing Papan PCB langsung. Kanggo kinerja RF dhuwur kanggo piranti, mangga sok dong mirsani panggonan seko modul. Ana telung cara kanggo nggunakake modul kanggo RF Modul karo antena PCB.
- Solution 1: optical solution. The RF module is placed on the side of the board, and the antennas are all exposed, and there is no metal material around the antenna, including wires, metal casings, piring bobot, lan liya-liyane.
- Solution 2: sub-optical solution. The RF module is placed on the side of the board, and the antenna below is hollowed out. There is a gap of not less than 5 mm reserved with the PCB, and there is no metal material around the antenna, including wires, metal casings, piring bobot, lan liya-liyane.
Solusi 3: Modul RF diselehake ing sisih pinggir papan, lan area PCB ing antena kosong, lan tembaga ora bisa dilebokake.
Saran Desain Peripheral
modul XT-ZB1 wis Integrasi menyang GPIO kacepetan dhuwur lan antarmuka Peripheral, kang bisa kui swara switch. Yen ana panjaluk dhuwur kanggo konsumsi daya lan karakteristik EMI, disaranake nyambungake resistensi serial 10 ~ 100 ohm, sing bisa nyuda overshoot nalika ngalih sumber daya, lan bisa menehi sinyal lancar. Ing wektu sing padha, uga bisa nyegah discharge elektrostatik (ESD).
