1.2.4. External Antenna
CH232BGN modules support internal antenna and external antenna options. If user selects to use an
external antenna,
CH232BGN
modules must be connected to the 2.4G antenna according to IEEE
802.11b/g/n standards. The antenna parameters required as follows:
Table 3: CH232BGN External Antenna Parameters
1.2.5. Evaluation Kit
An evaluation kit is available to assist users develop their applications. The evaluation kit, shown
below, allows the user to connect the CH232BGN module directly to an RS-232 port, 100Base-T
Ethernet port or Wireless port.
