Yes, all the currently available eS-WiFi modules are footprint compatible. (44 pin LGA)

Today, we recommend that you use a JTAG connector. We are currently working on two additional methods, use of the boot loader running inside the eS-WiFi or over the air. Over the air updates will require the use of an … Continue reading “How do I upgrade a eS-WiFi modules firmware?”

The module only require 6 wires to use the UART: TX, RX, Power, Ground and we recommend you also connect Reset and wake-up to your host.

There are two ways to rest the module. 1.) To do a Soft reset type the AT command  <ZR> Or 2.) Pull the module Reset pin low

1. Set Protocol to UDP 2. Set Local port number 3. Start UDP Comm Server EX. P1=1    Select UDP Protocol P2=5024    Set Port 5024 P5=1    Start UDP Comm Server

No, the module uses 3.3 volt logic.

Yes, all of the above.

You can use AT Commands over the UART, SPI or USB HID interface to send commands and send/receive data.

The eS-WiFi SPI interface is a slave.

Yes, the eS-WiFi modules support SPI. The correct pins to use for the host I/O are the ADC1-ADC4 pins. SPI_SCK=ADC2=Pin11 SPI_MISO=ADC3=Pin10 SPI_MOSI=ADC4=Pin9 SPI_NSS=ADC1=Pin12
