Sparkfun ESP32 Thing

I realised I had an old-ish esptool so I updated, no change.

I tried qio and that resulted in it rebooting constantly, eg

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

I also tried lowering the SPI clock to 26MHz and doing and erase & reprogram but no dice.
