Pulling up either one can achieve power-on. The chip inside the pin has a 200K pull-down resistor, and a 47K pull-up resistor is recommended. The pin thresholds are as follows: Regarding the WL_REG_ON pin of the 8800 module: It should be noted that the voltage level of this pin does not follow the VDDIO voltage. The PWR_WF pin is connected to a 47K pull-up resistor on the module, which pulls it up to 3.3V. Inside the chip, there is a 200K pull-down resistor, so the voltage of this pin is around 2.67V. If the baseboard does not require reset control for the module, the WL_REG_ON pin of the module can be left floating. Do not connect this pin to a 1.8V pull-up. Otherwise, it may cause abnormal power-on enable issues for the module. 7 Current consumption (Test Setintv 100) Parameter Test Item TX Power Current Unit WiFi TX 2.4G,11b, CCK,1Mbps 21dBm 390 mA 2.4G,11b, CCK,11Mbps 21dBm 330 mA 2.4G,11g, OFDM, 6Mbps 21dBm 380 mA 2.4G,11g, OFDM, 54Mbps 19dBm 300 mA 2.4G,11n,HT20, MCS0 20dBm 360 mA 2.4G,11n,HT20, MCS7 18dBm 290 mA 2.4G,11n,HT40, MCS0 20dBm 330 mA 2.4G,11n,HT40, MCS7 18dBm 180 mA 2.4G,11ax,HE20, MCS0 20dBm 320 mA 2.4G,11ax,HE20, MCS11 16dBm 170 mA 2.4G,11ax,HE40, MCS0 20dBm 300 mA 2.4G,11ax,HE40, MCS11 16dBm 170 mA 5G, 11a, OFDM, 6Mbps 19dBm 530 mA 5G, 11a, OFDM, 54Mbps 18dBm 350 mA 5G,11n,HT20, MCS0 18dBm 520 mA 5G,11n,HT20, MCS7 16dBm 330 mA 5G,11n,HT40, MCS0 18dBm 460 mA 5G,11n,HT40, MCS7 16dBm 260 mA 5G,11ac,VHT20, MCS0 18dBm 500 mA 5G,11ac,VHT20, MCS8 16dBm 250 mA 5G,11ac,VHT40, MCS0 18dBm 460 mA 5G,11ac,VHT40, MCS9 15dBm 230 mA 5G,11ax,HE20, MCS0 18dBm 480 mA 5G,11ax,HE20, MCS11 14dBm 250 mA 5G,11ax,HE40, MCS0 18dBm 450 mA 5G,11ax,HE40, MCS11 14dBm 200 mA Stop WiFi TX - - 66 mA WiFi RX - - 80 mA Stop WiFi RX - - 46 mA BLE TX BLE 1M 6dBm 100 mA Stop BLE TX - - 25 mA BLE RX - 38 mA Stop BLE RX - - 23 mA A880S-D40L SDIO/USB WiFi 2.4G/5G/BLE Module 8 RF Characteristics 8.1 WiFi 2.4G WLAN Transmitter Characteristics Parameter Test Item Typical Value CH1 CH7 CH13 Unit Output Power 11b,CCK, 1Mbps 20±2dBm,EVM<-18dB 21.15 21.05 21.07 dBm 11b,CCK,11Mbps 20±2dBm,EVM<-15dB 21.29 21.14 21.19 dBm 11g,OFDM, 6Mbps 20±2dBm,EVM<-15dB 21.29 21.14 21.19 dBm 11g,OFDM,54Mbps 19±2dBm,EVM<-30dB 21.29 20.94 21.07 dBm 11n, HT20 MCS0 20±2dBm,EVM<-15dB 20.28 20.00 20.21 dBm 11n, HT20 MCS7 18±2dBm,EVM<-36dB 17.72 17.95 18.16 dBm 11ax, HE20 MCS0 20±2dBm,EVM<-15dB 21.18 20.81 20.93 dBm 11ax, HE20 MCS11 16±2dBm,EVM<-36dB 16.60 16.86 17.06 dB…
